When an NI-DAQ device is selected in Motive, its device information gets listed under the Properties pane. Just basic information on the used device will be shown in the Properties pane. For configuring properties of the device, use the Devices pane.

For more information, read through the NI-DAQ setup page: NI-DAQ Setup.

Settings

Enabled

Only enabled NI-DAQ devics will be actively measuring analog signals.

Trigger Sync

This setting determines how the recording of the selected NI-DAQ device will be triggered. This must be set to None for reference clock sync and to Device for recording trigger sync.

• None: NI-DAQ recording is triggered when Motive starts capturing data. This is used when using the reference clock signal for synchronization.

• Device: NI-DAQ recording is triggered when a recording trigger signal to indicate the record start frame is received through the connected input terminal.

Trigger Terminal

(available only when Trigger Sync is set to Device) Name of the NI-DAQ analog I/O terminal where the recording trigger signal is inputted to.

Reference Clock Sync

This setting sets whether an external clock signal is used as the sync reference. For precise synchronization using the internal clock signal sync, set this to true.

• True: Setting this to true will configure the selected NI-DAQ device to synchronize with an inputted external sample clock signal. The NI-DAQ must be connected to an external clock output of the eSync on one of its digital input terminals. The acquisition rate will be disabled since the rate is configured to be controlled by the external clock signal.

• False: NI-DAQ board will collect samples in 'Free Run' mode at the assigned Acquisition Rate.

Reference Clock Terminal

(available only when Reference Clock Sync is set to True) Name of the NI-DAQ digital I/O terminal that the external clock (TTL) signal is inputted to.

eSync Output

Set this to the output port of the eSync where it sends out the internal clock signal to the NI-DAQ.

Rate

Shows the acquisition rate of the selected NI-DAQ device(s).

Device Channel Properties

Depending on the model, NI-DAQ devices may have different sets of allowable input types and voltage ranges for their analog channels. Refer to your NI-DAQ device User's Guide for detailed information about supported signal types and voltage ranges.

Min Voltage

(Default: -10 volts) Configure the terminal's minimum voltage range.

Max Voltage

(Default: +10 volts) Configure the terminal's maximum voltage range.

Terminal Type

Configures the measurement mode of the selected terminal. In general, analog input channels with screw terminals use the single-ended measurement system (RSE), and analog input channels with BNC terminals use the differential (Diff) measurement system. For more information on these terminal types, refer to NI documentation.

• Terminal: RSE Referenced single ended. Measurement with respect to ground (e.g. AI_GND) (Default)

• Terminal: NRSE NonReferenced single ended. Measurement with respect to single analog input (e.g. AISENSE)

• Terminal: Diff Differential. Measurement between two inputs (e.g. AI0+, AI0-)

• Terminal: PseudoDiff Differential. Measurement between two inputs and impeded common ground.

By modifying the device properties of the OptiHub, users can customize the sync configurations of the camera system for implementing external devices in various sync chain setups. This page directly lists out the properties of the OptiHub. For general instructions on customizing sync settings for integrating external devices, it is recommended to read through the guide.

While the OptiHub is selected under the , use the to view and configure its properties. By doing so, users can set the parent sync source for the camera system, configure how the system reacts to input signals, and also which signals to output from the OptiHub for triggering other external acquisition devices.

Synchronization Control

Internal Sync Freq (Hz)

This option is only valid if the Sync Input: Source is set to Internal Sync. Controls the frequency in Hertz (Hz) of the OptiHub 2's internal sync generator. Valid frequency range is 8 to 120 Hz.

Global Sync Offset (us)

This option is only valid if the Sync Input: Source is set to Sync In or USB Sync. Controls synchronization delay in microseconds (us) between the chosen sync source signal and when the cameras are actually told to expose. This is a global system delay that is independent of, and in addition to, an individual camera's exposure delay setting. Valid range is 0 to 65862 us, and should not exceed one frame period of the external signal.

Sync Input Settings

To setup the sync input signals, first define a input Source and configure desired trigger settings for the source:

• Internal/Wired sets the OptiHub 2 as the sync source. This is the default sync configuration which uses the OptiSync protocol for synchronizing the cameras. The Parent OptiHub 2 will generate an internal sync signal which will be propagated to other (child) OptiHub 2(s) via the Hub Sync Out Jack and Hub Sync In Jack. For V100:R1(legacy) and the Slim 3U cameras, Wired Sync protocol is used. In this mode, the internal sync signal will still be generated but it will be routed directly to the cameras via daisy-chained sync cables.

• Sync In sets an external device as the sync source.

Source: Internal/Wired

Internal Sync Freq (Hz)

This option is only valid if the Sync Input: Source is set to Internal Sync. Controls the frequency in Hertz (Hz) of the OptiHub 2's internal sync generator, and the this frequency will control the camera system frame rate. Valid frequency range is 8 to 120 Hz.

Source: Sync In

Source Frequency

Detects and displays the frequency of the sync signal that's coming through the input port of the parent OptiHub 2, which is at the very top of the RCA sync chain. When sync source is set to Sync In, the camera system framerate will be synchronized to this input signal. Please note that OptiHub 2 is not designed for precise sync, so there may be slight sync discrepancies when synchronizing through OptiHub 2.

Sync Offset

Manually adds global sync time offset to how camera system reacts to the received input signal. The input unit is measured in microseconds.

Input Trigger

Can select from Either Edge, Rising Edge, Falling Edge, Low Gated, or High Gated signal from the connected input source.

Input Divider

Allows a triggering rate compatible with the camera frame rate to be derived from higher frequency input signals (e.g. 300Hz decimated down to 100Hz for use with a V100:R2 camera). Valid range is 1 (no decimation) to 15 (every 15th trigger signal generates a frame).

Source: USB Sync

Source Frequency

Detects and displays the frequency of the parent source.

USB Sync-In Control

Allows the user to allow or block trigger events generated by the internal sync control. This option has been deprecated for use in the GUI. Valid options are Gate-Open and Gate-Closed.

Input Divider

Allows a triggering rate compatible with the camera frame rate to be derived from higher frequency input signals (e.g. 360Hz decimated down to 120Hz for use with a Flex 13 camera). Valid range is 1 (no decimation) to 15 (every 15th trigger signal generates a frame).}}

Input Trigger Options

External Sync Output

Pulse Type

Selects condition and timing for a pulse to be sent out over the External Sync Out jack. Available Types are: Exposure Time, Pass-Through, Recording Level, and Recording Pulse.

External Sync Output Options

Polarity

Selects output polarity of External Sync Out signal. Valid options are: Normal and Inverted. Normal signals are low and pulse high and inverted signals are high and pulse low.

By modifying the device properties of the eSync, users can customize the sync configurations of the camera system for implementing various sync chain setups.

While the eSync is selected under the Devices pane, use the Properties pane to monitor the eSync properties. Here, users can configure the parent sync source of the camera system and also the output sync signals from the eSync for integrating child devices (e.g. NI-DAQ). For a specific explanation on steps for synchronizing external devices, read through the following page: External Device Sync Guide: eSync 2.

Sync Input

Configure the input signal by first defining which input source to use. Available input sources include Internal Free Run, Internal Clock, SMPTE Timecode In, Video Gen Lock, Inputs (input ports), Isolated, VESA Stereo In, and Reserved. Respective input configurations appear on the pane when a source is selected. For each selected input source, the signal characteristics can be modified.

Synchronization Input Source Options

Sync Input Settings

Clock Freq (Hz)

Controls the frequency of the eSync 2's internal sync generator when using the internal clock.

Sync Offset (us)

Introduces an offset delay, in microsecond, to selected trigger signal.

Input Trigger

Sets the trigger mode. Available modes are Either Edge, Rising Edge, and Falling Edge, and each of them uses the corresponding characteristic of the input signal as a trigger.

Input Divider

Allows a triggering rate, compatible with the camera frame rate, to be derived from higher frequency input signals.

Input Multiplier

Allows a triggering rate, compatible with the camera frame rate, to be derived from lower frequency input signals. Available multiplier range: 1 to 15.

Final Frame Rate

Displays the final rate of the camera system.

Outputs

Allows you to configure signal type and polarity of synchronization signal through the output ports, including the VESA stereo output port, on the eSync 2.

Type: Defines the output signal type of the eSync 2. Use this to sync external devices to the eSync 2.

Polarity: Change the polarity of the signal to normal or inverted. Normal signals constantly output a low signal and pulses high when triggering. Inverted signals constantly output a high signal and pulse low when triggering.

Output Signal Types

Record Triggering

Trigger Source: Determines which trigger source is used to initiate the recording in Motive. Available options are Software, Isolated, and Inputs. When the trigger source set to software, recording is initiated in Motive.

Triggering with External Signals

With the eSync 2, external triggering devices (e.g. remote start/stop button) can integrate into the camera system and set to trigger the recording start and stop events in Motive. Such devices will connect to input ports of the eSync 2 and configured under the Record Triggering section of the eSync 2 properties.

By default, the remote trigger source is set to Software, which is the record start/stop button click events in Motive. Set the trigger source to the corresponding input port and select an appropriate trigger edge when an external trigger source (Trigger Source → isolated or input) is used. Available trigger options include Rising Edge, Falling Edge, High Gated, or Low Gated. The appropriate trigger option will depend on the signal morphology of the external trigger. After the trigger setting have been defined, press the recording button in advance. It sets Motive into a standby mode until the trigger signal is detected through the eSync. When the trigger signal is detected, Motive will start the actual recording. The recording will be stopped and return to the 'armed' state when the second trigger signal, or the falling edge of the gated signal, is detected.

Note: For capturing multiple recordings via recording trigger, only the first TAK will contain the 3D data. For the subsequent TAKs, the 3D data must be reconstructed through the post-processing reconstruction pipeline.

Steps

1. Open the Devices pane and the Properties pane to access the eSync 2 properties.

2. Under the Record Triggering section, set the source to the respective input port where the trigger signal is inputted.

3. Choose an appropriate trigger option, depending on the morphology of the trigger signal.

4. Press the record button in Motive, which prepares Motive for recording. At this stage, Motive awaits for an incoming trigger signal.

5. When the first trigger is detected, Motive starts recording.

6. When the second trigger is detected, Motive stops recording and awaits for next trigger for repeated recordings. For High Gated and Low Gated trigger options, Motive will record during respective gated windows.

7. Once all the recording is finished, press the stop button to disarm Motive.

When a camera, or a camera group, is selected from the Devices pane, related camera settings will be displayed in the Properties pane. From the Properties pane, you can configure the camera settings so that it is optimized for your capture application. You can enable/disable IR LEDs, change exposure length of the cameras, set the video mode, apply gain to the capture frames, and more. This page lists out properties of the cameras and what they are used for.

General Settings

Enabled

Enables/disables selected cameras. When cameras are disabled, they don't record any data nor contribute to the reconstruction of 3d data.

Rate

Shows the frame rate of the camera. The camera frame rate can only be changed within the devices pane.

Reconstruction

This setting determines whether or not selected cameras contribute to the real-time reconstruction.

Continuous Calibration

[Advanced] When this is set to on, the 2D data from selected cameras will contribute to the continuous calibration updates.

Rate Multiplier

Shows the rate multiplier or divider applied to the master frame rate. The master frame rate depends on the sync configuration.

Exposure

Sets the amount of time that the camera exposes per frame. The minimum and maximum values will depend on both the type of camera and the frame rate. Higher exposure will allow more light in, creating a brighter image that can increase visibility for small and dim markers. However, setting exposure too high can introduce false markers, larger marker blooms, and marker blurring--all of which can negatively impact marker data quality. Exposure value is measured in scanlines for tracking bars and Flex3 series cameras, and in microseconds for Flex13, S250e, Slim13E, and Prime Series cameras.

Threshold

Defines the minimum brightness for a pixel to be seen by a camera, with all pixels below the threshold being ignored. Increasing the threshold can help filter interference by non-markers (e.g. reflections and external light sources), while lowering the threshold can allow dimmer markers to be seen by the system (e.g. smaller markers at longer distances from the camera).

LED

This setting enables or disables the IR LED ring on selected cameras. For tracking passive retro-reflective markers, this setting must be set to true to illuminate the IR LED rings for tracking. If the IR illumination is too bright for the capture, you can decrease the camera exposure setting to decrease the amount of light received by the imager; dimming the overall captured frames.

Video Mode

Sets the video type of the selected camera.

IR Filter

Sets the camera to view either visible or IR spectrum on cameras equipped with a Filter Switcher. When enabled, the camera captures in IR spectrum, and when disabled, the camera captures in visible spectrum.Infrared Spectrum should be selected when the camera is being used for marker tracking applications. Visible Spectrum can optionally be selected for full frame video applications, where external, visible spectrum lighting will be used to illuminate the environment instead of the camera’s IR LEDs. Common applications include reference video and external calibration methods that use images projected in the visible spectrum.

Gain

Sets the imager gain level for the selected cameras. Gain settings can be adjusted to amplify or diminish the brightness of the image. This setting can be beneficial when tracking at long ranges. However, note that increasing the gain level will also increase the noise in the image data and may introduce false reconstructions. Thus, before deciding to change the gain level, adjust the camera settings first to optimize the image clarity.

Calibrated

[Advanced] This property indicates whether the selected camera has been calibrated or not. This is just an indication of whether the camera has been processed through the calibration wanding, but it does not validate the quality of the camera calibration.

Details

Basic information about the selected camera gets listed in the Details section

Number

Displays the camera number assigned by Motive.

Camera Type

Displays the model of a selected camera.

Serial Number

Displays the serial nubmer of a selected camera.

Displays focal length of the lens on the selected camera.

Display

Show Field of View

When this is enabled, the estimated field of view (FOV) of the selected camera will be shown in the perspective viewport.

Show Frame Delivery Info

Show of hide frame delivery information from the selected camera. The frame delivery information is used for diagnosing how fast each camera is delivering its frame packets. When enabled, the frame delivery information will be shown in the camera views.

Show Aim Assist Reticle

Show or hide the guide reticle when using the Aim Assist button for aiming the cameras.

Prime Color Camera

Prime color cameras also have the following properties that can be configured:

Resolution

Default: 1920, 1080

This property sets the resolution of the images that are captured by selected cameras. Since the amount of data increases with higher resolution, depending on which resolution is selected, the maximum allowable frame rate will vary. Below is the maximum allowed frame rates for each respective resolution setting.

Compression Mode

Default: Constant Bit Rate.

This property determines how much the captured images will be compressed. The Constant Bit-Rate mode is used by default and recommended because it is easier to control the data transfer rate and efficiently utilize the available network bandwidth.

Constant Bit-Rate

In the Constant Bit-Rate mode, Prime Color cameras vary the degree of image compression to match the data transmission rate given under the Bit Rate settings. At a higher bit-rate setting, the captured image will be compressed less. At a lower bit-rate setting, the captured image will be compressed more to meet the given data transfer rate, but compression artifacts may be introduced if it is set too low.

Variable Bit-Rate

Variable Bit-Rate setting is also available for keeping the amount of the compression constant and allowing the data transfer rate to vary. This mode can be beneficial when capturing images with objects that have detailed textures because it keeps the amount of compression same on all frames. However, this may introduce dropped frames whenever the camera tries to compress highly detailed images because it will increase the data transfer rate; which may overflow the network bandwidth as a result. For this reason, we recommend using the Constant Bit-Rate setting in most applications.

Bit Rate

Default: 50

Available only while using Constant Bit-rate Mode

Bit-rate setting determines the transmission rate outputted from the selected color camera. The value given under this setting is measured in percentage (100%) of the maximum data transmission speed, and each color camera can output up to ~100 MBps. In other words, the configured value will indirectly represent the transmission rate in Megabytes per second (MBps). At bit-rate setting of 100, the camera will capture the best quality image, however, it could overload the network if there is not enough bandwidth to handle the transmitted data.

Since the bit-rate controls the amount of data outputted from each color camera, this is one of the most important settings when properly configuring the system. If your system is experiencing 2D frame drops, it means one of the system requirements is not met; either network bandwidth, CPU processing, or RAM/disk memory. In such cases, you could decrease the bit-rate setting and reduce the amount of data output from the color cameras.

Image Quality

The image quality will increase at a higher bit-rate setting because it records a larger amount of data, but this will result in large file sizes and possible frame drops due to data bandwidth bottleneck. Often, the desired result is different depending on the capture application and what it is used for. The below graph illustrates how the image quality varies depending on the camera framerate and bit-rate settings.

Gamma

Default : 24

Gamma correction is a non-linear amplification of the output image. The gamma setting will adjust the brightness of dark pixels, mid-tone pixels, and bright pixels differently, affecting both brightness and contrast of the image. Depending on the capture environment, especially with a dark background, you may need to adjust the gamma setting to get best quality images.

The Properties pane can be accessed by clicking on the icon on the toolbar.

The Properties pane lists out the settings configured for selected objects. In Motive, each type of asset has a list of associated properties, and you can access and modify them using the Properties pane. These properties determine how the display and tracking of the corresponding items are done in Motive. This page will go over all of the properties, for each type of asset, that can be viewed or configured in Motive.

Advanced Settings

The Properties pane contains advanced settings that are hidden by default. Access these settings by going to the menu on the top-right corner of the pane and clicking Show Advanced and all of the settings, including the advanced settings, will be listed under the pane.

The list of advanced settings can also be customized to show only the settings that are needed specifically for your capture application. To do so, go the pane menu and click Edit Advanced, and uncheck the settings that you wish to be listed in the pane by default. One all desired settings are unchecked, click Done Editing to apply the customized configurations.
