基于机器视觉的二步定位算法研究

he traditional coordinate measuring machine can only be pulled by operators to complete the surface measurements. During the process of introducing Machine vision technology into the CMM measurement, one of the key technologies is the positioning of measured surface, the traditional positioning algorithm is huge-workload, time-consuming and can not meet the real time requirements for CMM .This paper suggest a position located method by using a rectangular box and curve. Details of the orientation algorithm, experiments prove that the algorithm meets the positioning accuracy and it can improve the efficiency of coordinate measuring machine measurements.
