The invention provides a laser scanning measurement device. The laser scanning measurement device comprises a three-dimensional laser scanner used for carrying out laser scanning measurement and outputting coordinate system point cloud data, a GNSS/IMU combined positioning attitude determination system used for carrying out calculation according to GNSS data and IMU data to acquire time position attitude data, a panorama camera used for acquiring panorama image data containing position and attitude data, a point cloud data processing system used for calibrating scanner parameters according to the coordinate system point cloud data and the time position attitude data to generate WGS84 coordinate system laser point cloud, and a three-dimensional model modeling system used for carrying out three-dimensional model data establishment according to the coordinate system laser point cloud and the panorama image data. The laser scanning measurement device is advantaged in that the laser scanning measurement device can be widely applied to the three-dimensional digital city, general urban management part survey, highway reorganization and expansion, traffic infrastructure measurement, mine three-dimensional measurement, navigation channel embankment measurement and island reef shoreline three-dimensional measurement fields.
