In order to obtain urban three-dimensional spatial information quickly and efficiently,the land-based mobile laser scanning mapping system based multi-sensor integration technology is designed.In this system,ring laser gyro(RLG) strapdown inertial measurement unit(SIMU),DGPS and odometer constitute the high-accuracy position and orientation system(POS) to provide positional and orientation information of the mapping.Major with laser scanner,supplementary with CCD camera and SVHS camera,the digital imaging system is constituted to acquire digital imaging information.Under control of the land-based computer system,both of these systems accomplish mapping data synchronous acquisition and storage.By means of post-procession,all kinds of data is matched and coordinated.Thus urban three-dimensional actual scene modeling can be constructed.
