The Image Process Technology of Micro-Detection for Jet-Pan Based on CCD

The jet-pan is a key part of jet-pan servo valve, working performance of the servo valve is directly affected by the machining quality. This paper has realized the high precision measurement on dimension and position accuracy of the jet-pan through the research on CCD optical micro-detection technology. The result of image processing will affect the measuring accuracy directly during the detection, so this paper will put emphasis on discussing the image processing algorithm in the detection of the jet-pan. Through a series of algorithmic combination, this paper will achieve the image process and finally obtain the result.
