Abstract：In order to ensure the quality of chip strips,manufacturers need to detect defects of chip packages.With the contin-uous improvement of production efficiency,it is urgent to design a multiple production lines detection method with low cost and high efficiency.Therefore,the defect detection technology based on mobile GPU is carried out,using the large number of parallel threads in GPU and assigning a single thread for each image to improve detection efficiency.Each thread uses image processing methods for feature analysis and detects different areas in image.Experimental results show that when detecting 50 production lines and each strip image has 10 areas to be detected,our method achieves a 15.02x speedup compared to the CPU detection method.
