Abstract

A control system of a three-dimensional laser scanning device disclosed by the present invention comprises a laser ranging module, a power supply module, a processor module, a motor driving and subdivision module, a mechanical rotating and scanning mechanism, an angle feedback module, a network transmission module and an upper computer. The control system integrates the functions as one, such as the laser scanning control, the data transmission, the data visualization, etc., can operate and control the three-dimensional laser scanning device to obtain the three-dimensional scene information of the space accurately, thereby enabling the physical scenes to reappear really and tridimensionally. Meanwhile, the interaction of a scanning device lower computer and the upper computer is realized, the operation personnel can send the control commands to the scanning device lower computer via the upper computer to set the parameters, such as the scanning resolution ratio, the scanning modes, etc., and the upper computer receives the point cloud data sent by the scanning device lower computer to denoise, smooth, visualize and the like. The control system disclosed by the present invention has the characteristics of being strong in feasibility, low in cost and convenient in networking.

Description

technical field [0001] The invention belongs to the technical field of control engineering and control system design, and more specifically relates to a control system of a three-dimensional laser scanning device. Background technique [0002] Three-dimensional laser scanning measurement technology is a space measurement technology that has developed rapidly in recent years, and is known as a technological revolution in the field of surveying and mapping technology. 3D laser scanning technology can quickly and accurately obtain the 3D coordinates of scene space points, and then completely reproduce the real physical world, so it is also called "real scene replication technology". Compared with the traditional method of collecting spatial point coordinates point by point, 3D laser scanning has the characteristics of high precision, fast collection speed, intelligent scanning and massive measurement points. The application of 3D laser scanning technology to engineering survey ...
