摘　　要：针对断路器长延时调整时对脱扣螺钉自动快速定位的难题,提出了基于视觉图像的脱扣螺钉定位方法。通过工业CCD相机获取断路器三相双金属片上脱扣螺钉的图像信息,利用开源的计算机视觉库(Open CV)软件进行图像处理提取螺钉中心位置,从而将其坐标位置传送给下位机PLC控制同心双柔轴调整机构对螺钉螺母完成长延时调整动作。该视觉定位系统已进入试验阶段,系统稳定可靠,实现了螺钉的快速、精确定位,将断路器长延时测试时间缩短了30%以上。Aiming at the problem of how to automatically and quickly locate the release screw in circuit breakers long delay test,a release screw positioning method based on vision image was studied in this paper. An industrial CCD camera was used to get image information of the three-phase release screws. OpenCV software was used for image processing to extract the screw center position. Thereby,the position value was transferred to lower machine PLC to control concentric double soft shaft adjustment mechanism for completing lapse adjusting action. This visual positioning system enters the test stage,and the system is stable and reliable. Fast and accurate positioning is realized,and the circuit breakers long delay testing time reduces more than 30%.
