摘　　要：提出了一种基于CCD的组合式测量系统,该系统主要由多个CCD摄像机和便携式扫描仪组成。多个CCD摄像机主要根据测量对象的尺寸和特征需要自行布置,利用CCD空间定位原理,提取终端便携式扫描仪上特征点坐标,得到便携式扫描仪实时姿态并计算出相应的坐标转换参数,以达到多视角图像自动拼合的目的。还利用上述组合式测量方法对观音模型进行了测量实验,测量结果表明该系统有助于测量点云数据的自动拼合,从而实现对大尺寸复杂曲面物体测量。This paper presents a combined measurement system based on CCD,the system consists of multiple CCD cameras and portable measuring instrument components.Multiple CCD cameras are mainly arranged according to the needs and characteristics of the measurement object size,with CCD positioning principle,getting the coordinate of feature points on measuring instrument,to real-time gesture of portable measuring instrument and calculates the corresponding coordinate transformation parameters,in order to achieve more perspective automatic image registration.According to the combined measurement method,the paper do the measuring experiments of Guanyin model,which indicates that the measurement system can be used to automatic registering cloud data of points,so as to realize the measurement of complex surface of large size object.
