| Abstract: | This paper proposes a selLtuning algorithm for the low threshold value by analyzing the distribution of pixel gradient with the purpose of facilitating accurate positioning information for coordinate meas- uring machine. Experiments have prove that improved algorithm can remove isolated noise and enhance the weak edge information, which will offer better locating information to the three coordinate measuring machine. |
