6.Ground Calibration

1. Before using this function, please calibrate the system first by Initial Calibration. After the calibration is completed, place the Marker surface calibration point on the site. It is necessary to place 3-5 Marker points in the capture scene, and ensure that the position of the placed Marker points is in the even part of the capture scene.

Ground Calibration:

Switch to 2D view, click on Calibration, select Ground Calibration, keep default parameters and name, double-check the number of marker points in the area, click on Calibration. After calibration, all midpoints in the 3D view should be on the ground. Click on Save, a file dialog will appear, click OK (8.6.1).

The number of marker points must be greater than 3, and there should be no other extraneous points in the area except for the placed points.

Height Offset:

When specifying the radius for the Marker, please reference a point. Ensure that after calibration, the Marker will be displayed completely on the ground.

The default is 0.

Note: The unit of measurement for the value is in millimeters.
