Abstract

The present invention relates to a three-dimensional scanning system for acquiring three-dimensional data of an object. The system comprises a projector and a scanner. The projector is used for projecting a feature image of a first wave band to a scanned object, the feature image comprises a plurality of key features. The scanner comprises a projection module for emitting scanning light of a second wave band to the surface of the scanned object, a first acquisition module used for collecting a feature image projected to the scanned object and obtaining key feature three-dimensional data projected to the surface of the scanned object, a second acquisition module used for collecting scanning light of a second wave band reflected by the scanned object and obtaining dense three-dimensional point cloud data of the surface of the scanned object, wherein, the first wave band and the second wave band do not interfere with each other. According to the three-dimensional scanning system providedby the invention, the collection of the feature image of the first wave band and the collection of the reflected scanning light of the second wave band do not interfere with each other, and the collected three-dimensional data is more accurate.

Description

technical field [0001] The invention relates to the field of three-dimensional digitization, in particular to a three-dimensional scanning method and system. Background technique [0002] The current 3D scanning method requires manual sticking, marking points or features on the surface of the object to be measured, and using photogrammetry to shoot the marking points and obtain their 3D data; then import the 3D data of the marking points or features, and use a scanner Splicing and scanning is performed around the object to be measured using marker points or features. After scanning, it is necessary to manually remove the stickers, which wastes time and manpower. SUMMARY OF THE INVENTION [0003] Based on this, it is necessary to provide a three-dimensional scanning method and system for the problem of time-consuming and labor-intensive acquisition of feature data by manual sticking. [0004] A three-dimensional scanning system for acquiring three-dimensional data of an ob...
