摘要
道路标志的尺寸和高度信息是道路养护管理的2个主要内容。针对道路标志测量工作的艰巨性和危险性,设计了基于CCD摄像机、速度传感器、陀螺仪和采集车等仪器组成的数字图像测量系统;分析了测量过程中各坐标系之间的转换关系;给出了数字图像测量系统的框架图和基本原理;并结合一个道路标志尺寸测量算例,证明该系统测量结果的准确性。
The position and high information of the road sign are two of the main contents of road maintenance management. Against the arduousness and dangerous of the measure work to the road sign, a digital picture measuring system is designed on the basis of CCD camera, distance sensor, gyroscope, etc.. The conversion relation between every coordinate in the course is analyzed. The frame picture and basic principles of the digital picture measuring system are provided. The results of the system are proved accurate by utilizing a road sign measure example.
