Mount or Place the Calibration Board
When a calibration board is used for the intrinsic parameter check or intrinsic parameter correction, you should place the calibration board according to the instructions in Intrinsic Parameter Tool.
If the camera is used in 3D Robot Guidance projects, please mount or place the calibration board according to the instructions in Mount the Calibration Board.
