Three-dimensional scanning system and method

Abstract

The invention is suitable for the technical field of three-dimensional scanning and provides a three-dimensional scanning system and method. The system comprises three-dimensional scanning equipment, control equipment and a rotating platform. Under the control of the control equipment, a to-be-scanned object is driven by the rotating platform to rotate for a circle in sequence according to preset rotation angles; the three-dimensional scanning equipment is used for acquiring the three-dimensional information of the to-be-scanned object after the rotating platform rotates in a forward direction for the preset rotation angles every time under the control of the control equipment to obtain multiple groups of three-dimensional scanning data; the control equipment comprises a three-dimensional model acquisition unit. The three-dimensional model acquisition unit is used for registration and fusion on the multiple groups of three-dimensional scanning data to obtain an integrated three-dimensional model of the to-be-scanned object. According to the three-dimensional scanning system and method provided by the invention, manual operations are not needed, and manual labeling auxiliary registration processing is not needed, and therefore, full-automatic acquisition of the three-dimensional information of the object is realized. Compared with the prior art of manual operations, the three-dimensional scanning system and method are remarkably improved in scanning efficiency and registration accuracy.

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 and method. 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 me...
