Description

technical field [0001] The invention belongs to the technical field of three-dimensional scanning, and in particular relates to a three-dimensional scanning device. Background technique [0002] A 3D scanner is a scientific instrument used to detect and analyze the shape and appearance data of objects or environments in the real world. By creating a point cloud of the geometric surface of the object, the collected data is used for 3D reconstruction calculations (the more intensive point cloud can create a more accurate model). These models have a wide range of uses, such as industrial design, defect detection, reverse engineering, robot guidance, landform measurement, medical information, biological information, criminal identification, digital cultural relic collection, film production, game creation materials, etc. application. [0003] Due to the limited scanning range of the three-dimensional scanner, the existing three-dimensional scanning device usually uses a hand-h...

Problems solved by technology

[0004] 1. The scanning method of the handheld scanner increases the workload of the staff. At the same time, the movement of the handheld scanner during the scanning work will cause the local scanning points to be uneven due to the irregularity and unevenness of the staff's hand-held movement. , so that the point data is not accurate enough;

[0005] 2. The fixed position scanner scans the object by rotating the electric turntable. Although the scanning is uniform, when scanning the bottom of the workpiece, it needs to be turned over manually, which is not convenient enough, and the position of the scanner cannot be adjusted;
