Abstract

The invention relates to the technical field of space scanning and discloses a space scanning system based on a unmanned aerial vehicle (UAV) carrier and structured light scanning technology and a working method thereof. The present invention provides a space scanning system platform integrating a structured light sensor, a CMOS image sensor, an acceleration sensor, and a gyro sensor and the likeand employing a drone as a carrier; based on real-time motion attitude data, multiple frames of point cloud data stream can be spatially superimposed to obtain three-dimensional scene data of an entire scanning area; an aim of dynamic spatial scanning can be attained based on flexibility of small UAVs and mature structured light three-dimensional scanning technology. In addition, the space scanning system is advantaged by high degree of scanning automation, high stability of point cloud data scanning, diversification of output file formats, simple structure and the like; the system and the method are convenient to promote and use.

Description

technical field [0001] The present invention relates to the technical field of three-dimensional scanning, in particular to a space scanning system based on unmanned aerial vehicle and structured light scanning technology and its working method. Background technique [0002] Structured light three-dimensional scanning technology is a high-speed and high-precision three-dimensional scanning measurement method. Composite 3D non-contact measurement technology of vision technology. Using this measurement principle, it is possible to perform photogrammetry on the object (the so-called photogrammetry is similar to the camera taking pictures of the objects in the field of view, the difference is that the camera captures the two-dimensional image of the object, and the developed measuring instrument obtains What is the three-dimensional information of the object) becomes possible. In addition, unlike traditional 3D scanning technology, structured light 3D scanning technology can m...
