Three-dimensional measuring system and three-dimensional scanning device thereof

Abstract

The invention relates to a three-dimensional measuring system. The system comprises: a positioning and attitude determining device; a laser scanner, which has a 360-degree scanning field and is used for obtaining geometric data of a measured target object by scanning; an electronic rotary table, which has a rotary center and makes horizontal rotation movements by circling the rotary center; a positioning and attitude determining device, which is used for obtaining absolute position data of the electronic rotary table; and a data processing device, which is used for carrying out fusion processing on the absolute position data of the electronic rotary table and the geometric data obtained by the laser scanner. The positioning and attitude determining devices and the laser scanner are installed on the electronic rotary table; and a specific angle is formed between a scanning surface of the laser scanner and the electronic rotary table. In addition, the invention also provides a three-dimensional scanning device. The three-dimensional measuring system and the three-dimensional scanning device thereof enable omnibearing scanning and measurement on a measured object to be realized.

[0002] With the increasing popularity of three-dimensional spatial information services, people have higher and higher requirements for the fidelity of virtual reality, and mobile modeling and measurement technology has attracted more and more attention. The movement carriers of mobile measurement equipment are various, which can be land vehicles. , Ships, aviation vehicles, and even portable backpacks, so they are widely used. Mobile modeling and measurement technology uses laser scanners to directly obtain the geometric information of the measurement target. The working distance can reach the kilometer level, and the distance measurement can also reach However, due to the limited field of view of the laser scanner, it can only scan the target in a specific direction and cannot achieve omni-directional scanning. This cannot meet the specific needs of some users for scanning angles. For example, it cannot meet the needs of railway Departmental requirements for surveying high voltage lines above railway tracks, difficulty obtaining point clouds for oncoming traffic signs, or being able to scan only one side of an alley but not the other
