摘要: 为实现空间信息的快速及高效获取,在集成GNSS、IMU、全景相机、激光雷达等主要传感器的基础上,研制了车载全景激光耦合式移动测量系统。根据精密解算的位置姿态信息,对全景影像和激光点云进行了耦合,生成含有真彩色点云的可量测实景影像,提出鸟瞰实景影像、基于浏览器的海量点云网络发布等点云应用新形式。该系统在渝武高速公路扩能改造工程快速移动测量中的成功应用,证明系统不仅安装简便、采集快速、处理高效、成果丰富,而且具备厘米级的测量精度,有效提高了空间信息的获取及处理效率。

Abstract: To realize the fast and efficient acquisition of spatial information, a vehicle mobile mapping system is developed on the basis of integrating sensors such as GNSS, IMU, panoramic camera and LiDAR. According to the precision solution of position and orientation, the panoramic image and the laser point cloud are coupled to generate a measurable panorama with true color point cloud. New forms of application are also brought out, such as the aerial view panorama and the browser-based massive point cloud publishing. The successful application of the system during the rapid mobile mapping in the Yuwu Expressway expansion project has proven that the system not only has the advantages of simple installation, rapid acquisition, high efficiency, fruitful results, but also has the measurement accuracy of centimeter level.

Key words: vehicle mobile mapping system, coupling of panorama and laser point, measurable panorama, Web publishing of massive point cloud, aerial view panorama
