[0002] The laser scanning system is mainly composed of a laser scanner, a computer, a power supply system, a bracket, and system supporting software. As the main component of the laser scanning system, the laser scanner is composed of a laser emitter, a receiver, a time counter, a filter, a control circuit board, and software.

[0003] Laser scanners use the principle of laser ranging. By recording the three-dimensional coordinates, reflectivity, texture and other information of a large number of dense points on the surface of the measured object, the laser scanner can quickly reconstruct the three-dimensional model of the measured object and various drawing data such as lines, surfaces and bodies. Laser scanners use high-speed laser scanning measurement methods to quickly obtain the three-dimensional coordinate data of the surface of the measured object with high resolution over a large area. They can quickly and massively collect spatial point information, providing a new technical means for quickly establishing a three-dimensional image model of the object. It has the characteristics of rapidity, non-contact, real-time, dynamic, active, high-density, high-precision, digitalization and automation. The laser scanning system includes the hardware part of data acquisition and the software part of data processing; according to the different carriers, the laser scanning system can be divided into several categories such as airborne, vehicle-mounted, ground and handheld; including two-dimensional laser scanners and three-dimensional laser scanners. Laser scanning technology is widely used in the fields of cultural relics protection, architectural planning, civil engineering, factory renovation, interior design, building monitoring, disaster assessment, ship design, digital city, etc. Utility Model Content
