3D measurement is performed with a combination of two or three cameras. In order to accurately measure the height direction, the position of each camera must be accurately determined and the coordinates of two cameras must be linked. This procedure is referred to as "3D coordinate setting" and a custom calibration tool is used.

This is a coordinate system to indicate the spatial position of an object. It is used to handle displaying and moving of an object. In order to express the measurement in the coordinate system (world coordinate system) of an external device (such as industrial robot), the measurement must be converted to the world coordinate system. This operation is referred to as "world coordinates".
The parameters used for the world coordinates are produced by photographing the calibration target with a camera and performing sampling measurement at several locations.

Specify the conditions for inputting images from the camera and for storing images of the measured objects.

Also, set up for linking the coordinates of the two cameras for 3D measurement and the settings for converting the coordinates to the spatial coordinates (the world coordinates).
