【Abstract】 On the image processing of vision tracing weld line, there are large quantity of data information with lots of interfere factors,the speed of image processing is very slow,which waste lots of computer running time.In order to improve the speed and enhance the timely accuracy of seam tracing, we pick up the main information and making threshold based on the characteristic of weld line image.On the base of experiment, the merit and demerit of artificial and automatic threshold are analyzed.it is resulted that the artificial threshold is fit for single image processing and the automatic threshold for muti image processing.更多还原
