摘要
针对当前齿轮缺陷检测过程中存在的问题,提出了一种基于Halcon软件开发的齿轮缺陷检测系统的设计方案,实现了测量系统中图像采集与显示、图像处理及运行控制等功能。首先控制转盘运行并利用CCD摄像机实时采集齿轮图像;然后进行图像预处理并对图像进行自动阈值化分割,获得齿轮的中心坐标和轮廓信息;最后基于形态学方法分析各个齿的尺寸并从中识别齿轮存在的缺陷。实验表明,该系统具有较高的测量精度和测量效率,能够满足实际生产的需要,为齿轮无损在线测量提供了新的途径。
Aiming at the existing problems in the process of gear defect detection, a design scheme of detection system is proposed based on the Halcon, and the functions of image acquisition, image dis- play, image processing and operation control, etc. of the system is realized. Firstly, the turntable is controlled and the CCD camera is used to collect the gear image. Then, the image is under preprocess- ing and image automatic segmentation, the gear center and contour are obtained. Finally, the gear size is analyzed and the defect is detected based on morphological method. The experiment shows that the system has high measuring precision and efficiency, can meet the needs of actual production, and a new way for gear nondestructive measurement is provided.
