(3) Unnamed point track is displayed
After the reference video calibration is completed, take the marker in the 3D view out of the field and put an unnamed point into the field. Find the "Video Overlay" function box under the "System" TAB in the Settings, and check the option of "unnamed point track" (as shown in Figure 205), that is, the unnamed point track display function, and then move the unnamed point.The trajectory of the unnamed point can be displayed in the reference video view (Figure 206).Note: When observing the track, it is necessary to ensure that there is only one unnamed marker point in the site. If multiple unnamed points appear, the track cannot be displayed.
The Track Time function indicates the track display time. You can click the arrow on the right to adjust the time (unit: s). The maximum time can be adjusted to 5s, and the default value is 1s.
