Transferring the coordinate system of a three-dimensional camera to the incident point of a two-dimensional camera

A non-transitory machine-readable storage medium encoded with instructions executable by a processing system including at least one processor, wherein, when executed by the processing system, the instructions cause the processing system to perform operations, the operations comprising:

• acquiring a three-dimensional coordinate system associated with a three-dimensional camera and a first reference point associated with the three-dimensional camera;
• acquiring a two-dimensional coordinate system associated with a two-dimensional camera and a second reference point associated with the two-dimensional camera;
• aligning the three-dimensional coordinate system with the two-dimensional coordinate system, based on a fixed and known positional relationship between the first reference point and the second reference point, to obtain a fixed positional relationship between the three-dimensional coordinate system and the two-dimensional coordinate system;
• and
• transferring the three-dimensional coordinate system to a datum point of the two-dimensional coordinate system, using the fixed positional relationship between the three-dimensional coordinate system and the two-dimensional coordinate system.
