Description

Technical Field

[0001] The utility model relates to the technical field of three-dimensional scanning equipment, in particular to a three-dimensional scanning device. Background Art

[0002] A stereoscopic scanning device is a device used to capture and record the three-dimensional shape and structure of an object or environment. It uses various technologies (such as laser, structured light, photogrammetry, depth sensing, etc.) to generate accurate three-dimensional models. This device is widely used in industrial design, cultural relics protection, architecture, medicine, film and television production and other fields.

[0003] A Chinese patent with patent publication number CN212860488U discloses a three-dimensional scanning device for 3D printing, including a mounting base, a top plate located directly above the mounting base, and a first scanning head. The mounting base and the top plate are both cylindrical disk structures, and the diameters of the mounting base and the top plate are the same. The first scanning head is fixedly mounted on the bottom end surface of the top plate by bolts.

[0004] Most existing three-dimensional scanning devices have a fixed scanning head, but this setting will result in blind spots during scanning, or require frequent adjustment of the object's position, resulting in poor scanning results and cumbersome operation. Therefore, it is necessary to develop a three-dimensional scanning device that can automatically scan objects in all directions. Utility Model Content
