Mass-target image matching algorithm based on self-constructed multi-window

An algorithm of mass-target image matching for vision measurement in mass chip production was put forward to carry out multi-window self-construction. Spiral character chain was used to modify maximum close distance (MCD) for improving the speed and robustness. Experimental results confirm that the assignment of recognizing mass chips is achieved by the algorithm. Beside the advantages of high speed and precision, it is flexible compared with other algorithms.
