Ground three-dimensional laser scanner and use method

Abstract

The invention discloses a ground three-dimensional laser scanner and a use method, and particularly relates to the technical field of three-dimensional laser scanning. The ground three-dimensional laser scanner comprises a machine body, the outer wall of the machine body is rotatably connected with a support frame, a tracking assembly is installed in the lower part of the support frame, and a protection assembly is installed in the upper part of the support frame. Through the arrangement of the tracking assembly, the reflecting prism of the three-dimensional laser scanner can accurately rotate along with the change of the orientation of the to-be-detected object on the ground, so that the reflecting prism and the to-be-detected object are always located on the same detection line, the orientation of the to-be-detected object is accurately and automatically tracked, the three-dimensional laser scanning precision is high, the scanning error is reduced, the accuracy of a data analysis result is improved, the practicability is high, through the arrangement of the protection assembly, the ground three-dimensional laser scanner can keep a working state in severe weather environments such as rain, snow and hail, the application occasion of the scanner is expanded, and the applicability of the scanner is improved.

Description

technical field [0001] The invention relates to the technical field of three-dimensional laser scanning, in particular to a terrestrial three-dimensional laser scanner and a usage method. Background technique [0002] The three-dimensional laser scanner is the main component of the three-dimensional laser scanning system. It is mainly 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 breaks through the traditional single-point measurement method and has the unique advantages of high efficiency and high precision. From the perspective of working method, the ground 3D laser scanner can be regarded as a non-prism total station with high-speed automatic angle measurement and distance measurement. Generally including scanner, control system and power supply system. The scanning system mainly includes laser ranging system, laser angle measuring system, instrument...

Problems solved by technology

[0005] To this end, the present invention provides a ground three-dimensional laser scanner and a method of use. By setting the tracking component, the reflective prism of the three-dimensional laser scanner can accurately rotate following the change of the orientation of the object to be measured on the ground, so that the reflective prism and the object to be measured can be accurately rotated. The object to be measured is always on the same detection line, and the orientation of the object to be measured is accurately and automatically tracked, so that the three-dimensional laser scanning accuracy is high, the scanning error is reduced, the accuracy of the data analysis result is improved, and the practicability is strong. Through the setting of the protective component , which can keep the ground 3D laser scanner in working condition under severe weather such as rain, snow and hail and various adverse environments, expand the application occasions of the scanner, and improve the applicability of the scanner to solve the problem of existing technologies Due to the inaccurate positioning between the measured object and the scanner, the accuracy of the observation results is low, and the ground 3D laser scanner is not suitable for bad weather, it is difficult to meet the requirements of various weather and bad environments, and the problem of low applicability
