Problems solved by technology

The triangulation method requires a lot of positioning parameters in the application, and it is very cumbersome and time-consuming in the calibration of the measuring equipment. If a certain parameter in the system cannot be accurately obtained during the actual measurement, it will cause errors in the measurement data
The measurement electronics are far more complex than the pulse method

Description

technical field [0001] The invention relates to a three-dimensional laser scanning device. Background technique [0002] Laser scanning is a technology for reconstructing target panoramic data and models from complex entities or real scenes. Laser scanners are successfully used in many fields, such as industrial surveying, topographical surveying, cultural relics protection, urban modeling, parallel inspection, reverse engineering and virtual reality, etc. [0003] Ranging information plays an important role in laser scanning. According to the principle of ranging, it can be divided into triangulation method, pulse method and phase method. The triangulation method is that a beam of laser light is irradiated on the object, and part of the diffusely reflected laser light is imaged on the photoelectric detection device through a prism. The triangulation method requires many positioning parameters in the application, and it is very cumbersome and time-consuming in the calibra...
