Abstract :
In this paper, we focus on electronics industry by now, in the manufacturing process, the servo system of the position of the alignment platen to do a study on methods of improving the software, which aims for the measurement system in the circuit board lamination. Characteristic marker can do accurate alignment. In our method, as do the pre-photographic image pre-processing to detect and record the image in the location of the marker, then according to the measurement system captured images do wavelet transform and reduce the image size to improve performance, supplemented by 2:1 candidate region search. That can do to enhance performance. By the actual experimental results can also be seen, this study found the correct way to position objects, and the time performance can finally improve.
