| 摘 要： | 障碍物检测问题一直是移动机器人的研究热点之一,也是机器人实现安全可靠导航的前提。文章利用激光测距雷达和机器视觉对障碍物进行联合检测,首先对摄像机标定,然后进行摄像机和激光测距雷达之间的联合标定,最后通过激光点数据将检测图像划分为几个小区域并进行图像处理。实验结果表明该方法能够有效检测出障碍物的大小信息,将检测图像划分为小区域也提高了图像处理的运算速度。

| Abstract: | Dynamic obstacle detection has been the research focus of the mobile robot, and is a prerequisite to achieve safe and reliable navigation for the robot. Joint detection of the obstacle using laser ranging radar and machine vision is introduced in this article. Camera is calibrated first, and then joint calibration between the camera and laser ranging radar is done, finally detected image is divided into several small regions through the laser point and image pro- cessing. Experimental results show that this method can effectively detect the size of the obstacle. The detected image divided into a small area also increased the speed of image processing operations. |
