一、引言车载移动测量技术是一种新兴的测量技术,也是当今测绘界最为前沿的科技之一。它是在机动车上装配全球导航卫星系统(GNSS)、相机系统(CCD)、惯性导航系统(INS)等先进的传感器和设备,在车辆高速行进中,快速采集道路及道路两旁地物的空间位置数据和属性数据,并同步存储在车载计算机系统中,事后基于点云与数字图像数据进行空间地理信息的提取与分析,形成内容丰富的空间信息数
I. Introduction Mobile measurement technology is an emerging measurement technology, but also one of the most cutting-edge science and technology in today’s surveying and mapping industry. It is equipped with advanced sensors and devices such as Global Navigation Satellite System (GNSS), Camera System (CCD) and INS, etc. in vehicles to quickly collect the space of road and roadside objects at high speed Location data and attribute data, and synchronously stored in the on-board computer system, afterwards based on point cloud and digital image data for spatial geographic information extraction and analysis to form a rich content of the number of spatial information
