Embodiment Construction

[0040] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0041] In the embodiment of the present invention, the three-dimensional scanning device performs three-dimensional scanning on the same object to be scanned from the side, bottom and top respectively, and the object to be scanned is placed above the transparent bottom plate, and the transparent bottom plate is driven by a rotating platform. The equipment performs three-dimensional scanning operations from different angles, and then automatically registers and fuses the side scan three-dimensional data set, bottom scan data set and top scan data set through the proposed automatic registration algori...

Abstract

The invention is applicable to the field of three-dimensional scanning technologies, and provides a three-dimensional scanning system which comprises three-dimensional scanning equipment, control equipment, a transparent bottom plate and a rotary platform. The rotary platform is controlled by the control equipment to drive the transparent bottom plate and a to-be-scanned object to respectively sequentially rotate by a circle according to preset rotation angles; the three-dimensional scanning equipment is controlled by the control equipment to acquire three-dimensional information of the side surfaces, the top and the bottom of the to-be-scanned object after the rotary platform forwardly rotates by the preset rotation angle in each procedure, so that three groups of three-dimensional data are acquired; the three groups of three-dimensional data are sequentially registered and fused by the control equipment, so that complete scanned data of the side surfaces, the top and the bottom of the to-be-scanned object can be obtained, and then are further registered and fused, and a three-dimensional model of the to-be-scanned object is obtained. The three-dimensional scanning system has the advantages that the three-dimensional information of the object can be automatically collected, and the scanning efficiency and the registration accuracy are obviously improved as compared with an existing manual operation technology.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional scanning, and in particular relates to a three-dimensional scanning system. Background technique [0002] The rapid development of 3D scanning technology has been applied to many fields and industries such as industrial inspection, design, animation and film special effects production, 3D display, virtual surgery, and reverse engineering. [0003] From the perspective of existing 3D scanning technologies, laser 3D scanning and projector-based structured light 3D scanning technologies are the main ones. The laser 3D scanning system projects laser lines or dot arrays, captures the projected laser features with a camera, and restores the 3D depth information of the object through triangulation. The main disadvantage of this point-by-point and line-by-line scanning method is that it is slow; In the structured light 3D scanning system of the instrument, it realizes the one-time measurement o...
