摘要:为解决传统工业机器人定位不精确、不灵活的问题,对机器视觉引导的工业机器人定位进行研究,提出以KUKA机械臂和嵌入式ZYNQ开发板为硬件平台的低成本系统方案。首先对工业机器人视觉定位抓取过程建立数学模型;然后研究基于机器视觉的图像处理技术,采用轮廓特征参数为辨识条件对预处理后的工件轮廓进行识别和定位;最后,经过坐标转换,将工件真实位姿发送给工业机器人控制系统进行抓取引导。实验结果表明,该系统对目标工件能够实现有效、精准的定位。

Abstract: In order to solve the problems of the traditional industrial robot control method,the positioning of industrial robots guided by machine vision was studied,and a low-cost system solution based on the KUKA robot arm and the embedded ZYNQ development board as the hardware platform was proposed. Firstly,a mathematical model was established for the visual positioning and grasping of industrial robots. Secondly,the image processing technology based on machine vision was studied,and the pre-processed workpiece contour was recognized and positioned with contour characteristic parameters as identification conditions. Finally,the real pose of the workpiece was sent to the industrial robot control system to guide grasping after coordinate conversion. Experimental results showed that the system could realize effective and accurate positioning of target workpieces.
