Method of Compressor Valve Edge Contour Recognition Based on Canny Operator

针对2D-90往复压缩机气阀装配过程中机器人对气阀边缘轮廓的识别问题,采用基于Canny算子的边缘检测方法,对压缩机气阀边缘轮廓信息进行提取,实现了机器人装配过程中的视觉引导,成功提取气阀轮廓。经实验验证,所用方法与传统方法相比,能有效抑制高斯噪声,且边缘线明确,无断点,有效提高边缘定位精度,满足实际工作要求。

Aiming at the problem of recognizing the gas valve edge contour by robot in the assembly process of 2D-90 reciprocating compressor,the edge detection method based on Canny operator was used to extract the edge contour information of the compressor valve,which realized the visual guidance in the assembly process of the robot and successfully extracted the valve contour.The experimental results show that compared with the traditional method,the proposed method can effectively suppress Gaussian noise,and the edge line is clear without breakpoints,which can effectively improve the accuracy of edge location and meet the requirements of practical work.
