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

Abstract

The invention discloses a simple type 3D laser scanning device which has a pedestal, a horizontal revolution platform, a support and a vertical pivot. The support is provided with a main transverse shaft and an auxiliary transverse shaft thereon. The main transverse shaft and the auxiliary transverse shaft are disposed horizontally and are mutually parallel, and can respectively rotate. The axial lead of the main transverse shaft and the vertical pivot are intersected. The axial lead of the auxiliary transverse shaft and the axial lead of the vertical pivot are intersected. A No. 1 main observatory apparatus is secured to the main transverse shaft. A No. 1 auxiliary observatory apparatus is secured to the auxiliary transverse shaft. A No. 1 auxiliary observation line and a No. 1 main observation line are with a same plane. The horizontal revolution platform, the main transverse shaft and the auxiliary transverse shaft rotate electronically. According to the invention, the device can be directly used in scanning without conducting tedious and time-consuming calibration in advance, is subject to substantially less influence imposed by ambient temperature and the like, can fully meet demands for precision in range finding, and is easy to operate.

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...
