Laser scanning measurement device

Abstract

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.

Description

technical field [0001] The invention relates to the field of surveying and mapping, in particular to a laser scanning measuring device. Background technique [0002] Street View is a reality map service. Provide users with 360-degree panoramic images of cities, streets or other environments, and users can obtain an immersive map browsing experience through this service. Through Street View, you can truly see high-definition scenes on the street as long as you sit in front of the computer. It is a good tool for traveling and driving, just like the GPS in people's hearts. [0003] But at present, the street view map can only be viewed, and the specification data (length, width and height) of the building cannot be obtained according to the street view map data. Contents of the invention [0004] The invention provides a laser scanning measuring device, comprising: [0005] 3D laser scanner, used for laser scanning measurement and output coordinate system point cloud data...
