| 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. |
