Abstract

The invention relates to a movable type three dimensional laser scanning system and a movable type three dimensional laser scanning method. A three dimensional point cloud scanning instrument and a sensing assembly are electrically connected with a first signal processor, and the three dimensional point cloud scanning instrument performs three dimensional scanning at different scanning positions and obtains corresponding point cloud data. A first signal processor updates the position and attitude information of the scanning centers of a movable scanning device in real time based on the data acquired by the sensing assembly and a simultaneous positioning and drawing algorithm, and the point cloud data corresponding to any scanning point is registered to a world coordinate system based on the real-time position and attitude information of the scanning centers. The sensing assembly measures the parameters needed by the simultaneous positioning and drawing algorithm. The system and method can automatically update the position and attitude information of the scanning centers during the scanning, so that the full-automatic registration is realized, the efficiency is improved, and the operation is simple.

Description

technical field [0001] The invention relates to the technical field of three-dimensional laser scanning, in particular to a mobile three-dimensional laser scanning system and a mobile three-dimensional laser scanning method. Background technique [0002] Three-dimensional laser scanners can be divided into short-distance measuring instruments and medium and long-distance measuring instruments according to their application occasions and measurement ranges. It has a wide range of applications, such as scenes in game development, interior design, measurement of vehicle parts design, accident scene restoration, national cultural heritage protection, archaeological work, etc. [0003] When the 3D laser scanner scans the scene data once, the measured data takes a scanning center as the reference point. Wherein, the scanning center usually refers to the origin of the coordinate system of the three-dimensional laser scanner. If multiple scans are required in a large scene, and th...
