| Abstract: | Machine vision technology was applied to process image and detect the speed sensor welding spots,CCD industrial camera was used to collect welding spots images of the speed sensor and determine the Region Of Interest(ROI)according to the characteristics of the image.The influence of salt and pepper noise was analyzed,and the median filtering algorithm was used to remove noise in welding spots images.Using OSTU algorithm to deduce the best threshold value and using the threshold value to segment the image.Using open operation algorithm to eliminate the small blocks generated by threshold segmentation.Using Open e Vision software algorithm library to calculate the welding spots area.Debugging the program of the detection system,and carrying out the actual production test.The results show that the testing system is accurate and efficient for the welding spot detection of the speed sensor. |
