Methods and Apparatus for Practical 3D Vision System

A method and system for specifying an area of interest in a 3D imaging system including a plurality of cameras that include at least first and second cameras wherein each camera has a field of view arranged along a camera distinct trajectory, the method comprising the steps of presenting a part at a location within the fields of view of the plurality of cameras, indicating on the part an area of interest that is within the field of view of each of the plurality of cameras, for each of the plurality of cameras: (i) acquiring at least one image of the part including the area of interest, (ii) identifying a camera specific field of interest within the field of view of the camera associated with the area of interest in the at least one image and (iii) storing the field of interest for subsequent use.
