Abstract: Arc light and splash,which have great influence on images,become key problems in image processing. According to the high speed of splash, effective methods, which reduce the disturbance of arc light through multi-images processing with AND operation and combining filter glasses, are represented in this paper. Moreover, because the width of laser strip is constant,and the laser strip is continuous,LOG filter and image segment filter are proved to be very effective. Scam tracking experiments show that all methods described above work very well.
