Background

The three-dimensional laser scanning technology is a new technology appearing in recent years, and can rapidly reconstruct a three-dimensional model of a measured object and various drawing data such as lines, surfaces and bodies by recording information such as three-dimensional coordinates, reflectivity, textures and the like of a large number of dense points on the surface of the measured object by utilizing the principle of laser ranging. Since the three-dimensional laser scanning system can densely acquire a large number of data points of the target object, the three-dimensional laser scanning technology is also referred to as a revolutionary technical breakthrough that evolves from single-point measurement to surface measurement, compared to the conventional single-point measurement. The technology also has many attempts, applications and exploration in the fields of historical relic protection, construction, planning, civil engineering, factory improvement, indoor design, building monitoring, traffic accident treatment, legal evidence collection, disaster assessment, ship design, digital cities, military analysis and the like.

Three-dimensional laser scanners are scientific instruments that detect and analyze the shape (geometry) and appearance data (such as color, surface albedo, etc.) of an object or environment in the real world. The collected data is often used to perform three-dimensional reconstruction calculations to create a digital model of the actual object in the virtual world. The three-dimensional laser scanner comprises a hardware part for data acquisition and a software part for data processing. According to the difference of carriers, the three-dimensional laser scanner can be divided into a handheld type, an airborne type, a vehicle-mounted type and a ground type.

The handheld three-dimensional laser scanner generally comprises a scanner body, a handle, a laser lens and two camera lenses, wherein the handle, the laser lens and the camera lenses are all arranged on the scanner body, and the two camera lenses are respectively arranged on two sides of the laser lens.
