摘　　要：采用视觉检测技术检测承压零件的气密性,通过提取零件承压时图像中有无气泡的产生,来判定零件是否存在泄漏,解决了传统的气密性检测方法检测效率低、准确性差的问题。以视觉检测技术和计算机数字图像处理技术为基础,设计了一套承压零件气密性检测的视觉检测系统。采用机械传动与气动相结合的传动方式,多工位检测,提高了气密性检测的效率。The tightness of the pressure parts of the visual inspection to detect whether the image extracting part confined bubble generated to determine the parts for leaks and to solve the traditional leak detection methods detection of low efficiency, poor ac- curacy. Visual detection technology and computer digital image processing technology as the basis for the design of a visual in- spection of the air tightness testing of the pressure parts. Transmission mode, using a combination of mechanical transmission with pneumatic multi-position detection, and improve the efficiency of the air tightness testing.
