5. Other Settings

Click on the Settings button on the toolbar above the software and select "Other Settings"（7.5.1）;

Camera

  1. Connection Timeout:The default connection timeout is 2 seconds. In environments with a small number of cameras, the connection duration can be set to 2-4 seconds. For larger numbers of cameras, the connection duration can be set to 4-8 seconds (manual modifications are not recommended unless necessary). Before making changes, please consult technical support engineers for guidance and minimize the operation to the tray.

  2. Data Mode:You can switch between "point mode" and "line mode"; the software defaults to "point mode." (Unless there are special requirements, please do not change this setting.)

Calibration

  1. Calculate Level:Before calibration, you can set the "Calculate Level". The default value of " Calculate Level" is 12. The larger the "Calculate Level" parameter, the longer the calibration calculation takes and the higher the accuracy. The smaller the parameter, the shorter the calculation time and the lower the accuracy.

  2. Masking Duration: On the calibration interface, selecting the automatic masking function specifies the duration for which automatic masking persists.

  3. T-calibrate Countdown:After clicking on T calibration in the T-shape, a countdown will appear on the interface. The countdown can be set according to your needs, with a default of 10 seconds.

Tracking and recognition

  1. 2D Constraint Threshold: The default is "1". This parameter controls the accuracy of 2D point extraction and should be adjusted based on factors such as site size, calibration results, marker size, etc. If you cannot extract points properly with a small number of cameras, you may increase this parameter appropriately. Please do not set this unless necessary, and consult a technical engineer before making adjustments.

  2. 2D Roundness Threshold: Effective in line segment mode, this parameter controls the accuracy of 2D point extraction. Please do not set this unless necessary, and consult a technical engineer before making adjustments.

    4o

  3. 2D Recognition Threshold: The default is "6". This parameter controls the accuracy of 2D point extraction and should be adjusted based on factors such as site size, calibration results, and marker size. Please do not set this unless necessary, and consult a technical engineer before making adjustments.

  4. Minimum Cameras Required:The default is "3". The minimum number of cameras for 3D reconstruction can be set to 2, meaning that at least 2 cameras are needed to simultaneously view this point for creating a 3D point. Unless necessary, please do not adjust this setting. Consult a technical engineer before making changes.

  5. 3D recognition threshold：The default is "6" mm. This parameter controls the extraction of 3D points. Please do not set this unless necessary, and consult a technical engineer before making adjustments.

  6. Rigid body recognition threshold：The default is "8" mm. This controls the allowable range of variation in the distance between rigid body points. Please do not set this unless necessary, and consult a technical engineer before making adjustments.

  7. Rigid Body Integrity Entrance Threshold: Default value is '85'. When identifying rigid bodies, if the number of points extracted in real-time from the current rigid body is greater than the number of marker points at the time of rigid body creation multiplied by the integrity threshold, the rigid body is recognized normally. If the number of points is less than the number of marker points at the time of rigid body creation multiplied by the integrity threshold, the rigid body cannot be recognized, and a white dot is displayed.

  8. Human recognition frame interval：Controls the number of times each human body template is recognized as a whole. If recognition fails in the previous frame, there will be a gap of a certain number of frames before trying again, preventing a drop in overall performance due to recognition attempts in every frame.

Smooth

  1. 3D Smooth:You can choose one of four smoothing levels: "1, 2, 3, or 4" based on the average number of smoothing points. Open the XYZ chart and select a point in the Marker in Live mode to reduce the fluctuation amplitude of the coordinate curve compared to without 3D smoothing.

  2. Kalman Smooth:When enabled, Kalman filtering is used to smooth the rigid body.

  3. Butterworth Smoothing: When enabled, applies Butterworth filtering to smooth the rigid body and human data.

  4. Eliminate Jitter:Eliminate jitter of all rigid bodies when they are stationary.

  5. Rigid Smooth:After creating a rigid body in Live mode, check Rigid Body Smoothing and set the displacement and rotation thresholds. The rigid body will then adhere to the set thresholds.

  6. Rigid smooth Secondary Switch:In the asset properties, add a new rigid body smoothness switch, which is off by default. The rigid body smoothness function only takes effect when both the rigid body smoothness master switch and the secondary switch in the asset properties are turned on.

  7. Edit Smoothing:You can choose "3-point smoothing, 5-point smoothing, or 7-point smoothing" to smooth the Marker points in Edit Mode.

  8. IK Compensation:In Live mode, when skeleton loss occurs in the human markerset, IK compensation calculates the position of the missing skeleton. If this function is not enabled, the IK calculation for the lost skeleton position will not occur.

  9. Redirect Data:This function is typically used to create and characterize a human body model. After selecting the "Retarget" checkbox, the characterized human body data will be broadcast and sent through the SDK.

Note: Not all scenes require the use of the smooth anti-shake function. In special scenes, when the shaking amplitude of points or rigid bodies in the 3D view is significant or needs to be reduced to meet requirements, the above function can be enabled accordingly. (Do not enable it unless necessary; please consult a technical engineer before setting it). When using VR scenes, 3D smoothing and Kalman smoothing can be combined to smooth the rigid bodies in the 3D view, reducing jitter in the VR scene.

Video Overlap

  1. **Show Unnamed Marker Track:**After calibrating the reference video, place an unnamed marker in the field and check the "Unnamed Point Trajectory" option to enable the unnamed point trajectory display function. At this point, move the unnamed point, and its trajectory will be displayed in the reference video view (7.5.2). Note: When observing the trajectory, ensure there is only one unnamed marker point in the field. If multiple unnamed points appear, the trajectory cannot be displayed.

  2. **Track Time:**Indicates the trajectory display time. You can click the arrow on the right to adjust the time in seconds, with a maximum of 5 seconds and a default of 1 second. The longer the time, the longer the unnamed point's trajectory will appear in the view. The longer the time, the longer the unnamed point's trajectory will appear in the view;

Display of R-Calc Marker

  1. R-Calc Marker Not Displayed on the Human Model;

  2. Real-Time Mode: After creating a rigid body in real-time, open the software settings, select "Other Settings," and enable "R-Calc Marker" .Right-click in the 3D view and select "Show R-Calc Marker" (7.5.3), and then green r -calculated markers will be displayed on the named points in the 3D view.

  3. In post-processing mode, if you want to display "R-Calc Marker", you need to click the solve button on the top toolbar.
