5. Template Creation

1. In real-time mode, when creating a human body, the model may encounter the following situations during movement:

   • Marker points on the human body are not recognized in the 3D view.

   • Marker points on the human body are incorrectly identified in the 3D view.

   • Marker points on the human body are missing.

2. This may occur due to sudden, excessive, or fast movements by the model during the motion process, or if the markers are obstructed.

3. Solution:

   • If you encounter similar situations as described above, you can record data for specific actions that tend to cause points to be unrecognized for repair purposes.

   • You can also refer to our "Calibration Exercise" video, mimic the movements demonstrated in the video for calibration, and record the process.

Repairing Missing Data Points

1. Before starting the template training, it is essential to repair the missing data frames in the motion capture data. For specific operational steps, please refer to the previous section "Twelve, Data Processing → (Four) Data Repair." If there is widespread missing data or a significant number of frames with missing points, it is not recommended to repair all of them. It is sufficient to repair only a few frames with missing data.

Training (Only applicable to human body)

Overwrite Training: This will recalculate the maximum and minimum values of the links within the selected range on the current progress bar. The calculated maximum and minimum values of the links will overwrite the original maximum and minimum values in the Mars file.

1. For example, after completing data repair, if a marker point remains unrecognized correctly across a series of consecutive frames, you can select a segment of continuous frames before or after this section where the marker point is correctly identified as the selection range.

2. Open the training window, set "Select Frames" as the training object, and click on the "Overwrite Training" button. This will update and overwrite the original maximum and minimum values of the links in the Mars file.

3. Next, include the consecutive frames with incorrect recognition within the selection range. Click on the "Track Identify" button. The new maximum and minimum values of the links, updated during the training, will be applied to the consecutive frames with incorrect recognition. The previously unrecognized points will also be correctly tracked and identified.

4. After completing the training, click on save in the asset panel, then go to "File" and select "Save Motion Capture Data." Switch to real-time mode, load the Markerset template created from the training, and click the play button to proceed.

Enhanced Training: Based on the Mars file template, the links are recalculated and updated. If the calculated maximum and minimum values of the links are larger or smaller than those in the template, they are updated. If the calculated maximum and minimum values fall within the range of the template's link values, no update is performed.
