Description

technical field [0001] The invention relates to the technical field of 3D laser scanners, in particular to a 3D laser scanner and a ranging scanning method thereof. Background technique [0002] The 3D laser scanning system is mainly composed of 3D laser scanner, computer, power supply system, bracket and system supporting software. As the main part of the 3D laser scanning system, the 3D laser scanner is composed of a laser emitter, a receiver, a time counter, a motor-controlled rotatable filter, a control circuit board, a microcomputer, a CCD machine, and software. It is a technological revolution after GPS technology in the field. It breaks through the traditional single-point measurement method and has the unique advantages of high efficiency and high precision. [0003] (1) During the use of the existing 3D laser scanner, the structure is relatively complicated, which is inconvenient for later maintenance and replacement work, and in the process of use, the data proce...

Problems solved by technology

[0006] The object of the present invention is to provide a 3D laser scanner and its ranging scanning method to solve the problem that the existing 3D laser scanners on the market have complicated structures and are inconvenient for the later stage in the process of use proposed by the above-mentioned background technology. Maintenance and replacement work, and in the process of use, the data processed by the 3D laser scanner is more noisy, which leads to the blurred surface of the exported model data, and the surface is not smooth enough, and the sampling efficiency of the 3D laser scanner is relatively low, which reduces the number of scanned objects. The problem of sampling efficiency and effect
