Part calibration algorithm used for robotic off - line programming

Abstract

With the application and development of off-line programming system ( OLPS) , as one of the key techniques for the application of OLP technology, robot calibration technique is drawing more and more attention. Aiming at part calibration for application of robotic off-line programming, part calibration algorithm is further discussed for adjustment and matching of part models by transformation matrix between part coordinates in the simulation environments and real workspace. Three part calibration methodologies: calibration of orthogonal plane part, four points calibration of circular reference part, and three points calibration of auxiliary feature points, are presented. Part calibration can be done by using the algorithm proposed only.
