This algorithm can be used as an effective precision detection technology. Crack Detection correct location, length features. With such high-speed computer technology development, computer for crack detection algorithm used to crack automatic detection system in many industries provides a powerful tool. It can be real and crack propagation behavior monitoring not only greatly reduced the labor is not realized before some ways. Dynamic digital image processing time and labor intensity, but also improve the measurement accuracy
