System and method for performing vision system planar hand-eye calibration from straight line features

A system for planar hand-eye calibration of a vision system using an object under manufacture having at least one feature, the object moving in at least one degree of freedom in translation or rotation on a motion stage, the system comprising:

• at least a first vision system camera and vision processor, the first vision system camera being arranged to acquire an image of a portion of a first linear feature on the object under manufacture, the imaged portion of the first linear feature excluding end points of the first linear feature, and track motion of the first linear feature throughout movement from a first position to a second position in response to moving of the motion stage in the at least one degree of translation;
• and
• a process that identifies the first linear feature in the first position and the second position along a two-dimensional (2D) plane and that computes a mapping between pixel positions in a pixel coordinate system of the first camera and physical positions in a motion coordinate system based upon locations of the first position and the second position.
