Functional principle of 3D data collection
The detection of the surface is carried out using 3D sensors comprising of at least two cameras and one projector.
Calibration target with registration marks
The cameras are calibrated using a special calibration target, i.e. the position and alignment of the cameras and other parameters are calculated.
Target
The striped pattern projected by the projector enable identical points to be found in both cameras using the Gray code and the phase shift method. Triangulation then enables the calculation of the x, y and z coordinates of the surface that are stored in a 3D point cloud.
