Abstract

The invention provides a time-sharing three-dimensional scanning system. The time-sharing three-dimensional scanning system is characterized by comprising a first image acquisition device, a second image acquisition device, a projection device and a sequential control circuit. Within a first period of time, the sequential control circuit controls the projection device to project first strip-structured light and synchronously controls the first image acquisition device to acquire first image data; and within a second period of time, the sequential control circuit controls the projection device to project second strip-structured light and synchronously controls the second image acquisition device to acquire second image data. The time-sharing three-dimensional scanning system provided by the invention can more accurately acquire a three-dimensional digital model of a stepped-surface-like structure on the surface contour of an object on the premise of no adjustment of positional relationship among a scanned object, the projection device and / or the image acquisition devices.

Description

technical field [0001] The present invention relates to a three-dimensional scanning system and method, in particular to a time-sharing three-dimensional scanning system and method. Background technique [0002] At present, the technical routes for obtaining a three-dimensional digital model of the oral cavity (or intraoral digital impression) through three-dimensional scanning mainly include extraoral scanning and intraoral scanning. There are two main methods of extraoral scanning: scanning positive models (for example, positive models made of materials such as reproduced plaster) and scanning impressions (for example, impressions made of materials such as silicone). The method of scanning the plaster positive model requires the doctor to first obtain the silicone impression (negative model) of the patient's dentition, and then pour plaster and other materials into the silicone impression to obtain the plaster positive model of the dentition, and finally scan the positive ...
