半智能排爆机器人单手双目手眼系统的研究

针对目前排爆机器人手动控制方式的不足,研究和开发了一个单手双目手眼系统用于半智能排爆机器人的自动控制.单手双目手眼系统是半智能排爆机器人的重要组成部分和关键技术,该视觉系统利用双目立体视觉原理,采用Matlab7.0作为运算引擎,调用机器视觉处理软件EVision6.2中的EasyMatch模式匹配库进行立体图像匹配,能实时捕获排爆机器人周围的图像信息、进行摄像机标定、图像预处理、立体图像匹配、确定机器人未端手爪与可疑目标物的相对位置坐标,并把图像实时显示在控制台,自动控制手臂靠近并准确地抓取可疑目标物.该半智能排爆机器人成功地抓取实验,表明了该立体视觉系统在精度上能够满足半智能排爆机器人的项目要求.

Research on Single-Hand and Binocular Visual System for Semi-Intelligent EOD Robot

Nowadays, the existing explosive ordnance disposal (EOD) robots usually are operated manually; it is very hard to operate. According to the theory of stereo vision, a new semi-intelligent explosive-handling robot with a binocular vision system is developed. The vision system captures real-time images, makes camera calibrations with Zhang’s method, preprocesses images, matches feature point, then gets the stereo coordinate of the feature point of the suspicious objects, programming with Matlab7.0 and the pattern matching library EasyMatch of machine vision software eVision, displays the real-time images on the console, finally, controls semi-intelligent explosive-handling robot to grasp the suspicious object automatically and accurately. Experimental results under variable lighting condition, variable shapes and variable distances indicate that the validity in real-time performance and precision of the vision system.
