Three-dimensional scanning system and three-dimensional scanning method

Abstract

The invention is applicable to the field of three-dimensional scanning technologies, and provides a three-dimensional scanning system and a three-dimensional scanning method. The three-dimensional scanning system comprises three-dimensional scanning equipment, control equipment and a rotary platform; the rotary platform is controlled by the control equipment to drive a to-be-scanned object to sequentially rotate by a circle according to a preset rotation angle; the three-dimensional scanning equipment is used for acquiring three-dimensional information of the to-be-scanned object under the control of the control equipment after the rotary platform forwardly rotates by the preset rotation angle in each procedure, so that a plurality of groups of three-dimensional scanned data can be acquired; the control equipment comprises a three-dimensional model acquisition unit and is used for sequentially registering and fusing the multiple groups of three-dimensional scanned data, so that a complete three-dimensional model of the to-be-scanned object is obtained. The three-dimensional scanning system and the three-dimensional scanning method have the advantages that artificial participation and artificial labeling registration auxiliary processing are omitted, so that the three-dimensional information of the object can be collected automatically, 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 particularly relates to a three-dimensional scanning system and method. Background technique [0002] Three-dimensional scanning technology has developed rapidly and 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] Judging from the existing 3D scanning technology, the laser 3D scanning and the projector-based structured light 3D scanning technology are the main ones. The laser 3D scanning system projects laser lines or lattices, 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 its slow speed; In the structured light three-dimensional scanning system of the instrument, it uses st...
