A 3D laser scanner for building model of ancient buildings

Abstract

The invention discloses a three-dimensional laser scanner for building models of ancient buildings, comprising: a base, the base is provided with four sets of screw rods inside, the four sets of screw rods are distributed in the middle of the four sides of the base, the The end of the screw rod is connected with the first driven gear and the middle part of the base is provided with a toothed plate, the toothed plate and the first driven gear are meshed with each other, and the surface of the screw rod is provided with a sliding block. In the present invention, an adjusting rod is arranged inside the mounting seat to rotate with the connecting rod, so that the second driven gear drives the driving gear to rotate, thereby driving the rotating shaft to rotate. The push rod and the connecting shaft, the electric push rod pushes the connecting shaft into contact with the 3D laser scanner, and clamps and fixes it. At the same time, the motor drives the connecting shaft to rotate through the drive chain, so that the 3D laser scanner can rotate vertically 360 degrees, and cooperate with the crawler wheels , which can realize the wide-angle shooting of the 3D laser scanner.

Description

technical field [0001] The invention relates to the technical field of three-dimensional scanning, and more specifically relates to a three-dimensional laser scanner for building models of ancient buildings. Background technique [0002] 3D laser scanning technology, also known as real scene replication technology, is a technological revolution in the field of surveying and mapping after GPS technology. It breaks through the traditional single-point measurement method and has the unique advantages of high efficiency and high precision. 3D laser scanning technology can provide 3D point cloud data of the scanned object surface, so it can be used to obtain high-precision and high-resolution digital terrain models. [0003] BIM (Building Information Modeling) technology was first proposed in 2002 and has been widely recognized by the industry around the world. It can help realize the integration of building information, from the design, construction, operation of the building t...

AI Technical Summary

Problems solved by technology

[0004] Existing 3D laser scanners are usually supported by a tripod stand when in use, and the three legs of the tripod stand need to be adjusted separately when adjusting the height, which is troublesome to adjust, and most of the existing 3D laser scanners are in use. The fixed structure makes it impossible to scan the entire ancient building. At the same time, due to the complex terrain, the mobile scanner will vibrate during the movement, which will affect the scanning accuracy of the scanner.
