(6) Template establishment
After the human body was created in the real-time mode, the Marker points of the human body in the 3D view were not recognized or identified incorrectly, the human skeleton was lost, the Marker points were lost, etc., which affected the human body effect. In the case of the above, please refer to our "calibration exercise" video, imitate the actions in the video to do calibration exercise and record. Then load the recorded video in post-processing mode and follow the steps below to create the template.After the completion of training, save the template, switch to the real-time mode, load the Markerset after the template is established, so that the human model recognition in real-time is more accurate.
Before the template is established, it is necessary to process the dynamic capture data first and repair the data frame of the lost point. For specific repair steps, please refer to "VIII. Data Processing → (V) Data repair" above. If the data has a large area of lost points or a large number of frames of lost points, it is not recommended to repair it.
After completing the repair of the motion capture data of the lost points, the next step is to process the Marker points that are not identified on the human body in the motion capture data. Firstly, in the first frame of data, click the "Template Creation" button above the software, select "All" for the frame range, click OK, and click Track identification. At this time, the Link between the points of all frames in the calibration operation data will be recalculated, and all frames will be tracked and identified once.
In the state of software suspension, slowly drag the data progress bar to observe whether there are unidentified Marker points on the human body in the 3D view. If there are unidentified Marker points, click the frame-by-frame play button to play the data frame-by-frame (as shown in Figure 126) and determine the frame from which the points are dropped.Once the name of the point is determined (you can skip to the frame that the point identifies correctly to view the point name in the Markers property bar on the right).
Click the quick id button, and the dialog box will pop up. Select the name of the unidentified point in the "Markers" property bar on the right side, and the name of the point in the quick id dialog box will also become the name of the selected point in the property bar (see Figure 127). Click the unidentified Marker in the 3D view.At this time, the Marker point has been correctly identified, and the Link connections between the Marker points have been automatically completed.
If the Marker is not recognized on multiple frames, the quick id lock function can be used to lock the quick id value when the quick id is used for recognition, so that the quick id value will not automatically increase after quick recognition, and a point can be used for recognition in the unidentified frame.Until the point is recognized on all frames.
What has just been fixed is that the unidentified point of the current frame is recognized, and then click template tracking or tracking recognition to identify this point and Link connection in all frames. Click the Template Creation button and select all frames for template creation update Link connection.
Repeat the above operations to repair the unidentified Marker points on other frames until all data is repaired. After confirming that all unidentified points in this set of data are repaired, skip the data to the first frame of data, click the template creation button, select "All", and check the option of "take the current frame as template", and click OK.Click the "File" button in the lower right corner, select "Save as model", select the saving path, enter the name of the model file, and click Save.
Switch to the real-time mode, click the "Add/Remove" button above the real-time mode, check the Mars file saved after the template is established, the model walks into the sport capture site, connect the camera to play.
