摘要:
行车操作人员在实际操作过程中,会出现对与之相邻障碍物之间的距离太近而不能及时规避情况,导致碰撞事故的发生. 针对这一问题,笔者构建了以ARM11微处理器为核心,以USB摄像头为图像采集设备的测距系统,在基于机器视觉和图像处理的基础上,将单目视觉和激光技术相结合,考虑对应点匹配和单个特征点提取误差对测量结果影响,将激光点作为特征点的单目视觉测距的方法. 实验结果表明,该系统能有效的测量与障碍物的距离,测量准确,可靠性高且满足实时性要求.
Abstract:
In the actual operation by crane operator, there exists the situation that operator can not make avoiding action timely at distance between crane and adjacent obstacles, causing collision accident. Aimed at this collision problem, we established distance measurement system by ARM 11 and USB camera. On the basis of machine vision and image procession, considering the effect of corresponding point match and extraction deviation of single characteristic point on measurement result, we integrated laser technology into monocular vision and adopted the monocular vision method of distance measurement using single laser point. The test result indicates that this system can effectively measure the distance of obstacles with accurate measurement and high reliability, meeting real-time requirement.
