Abstract

A method, device and system for reconstructing three-dimensional data of teeth. The method comprises: acquiring a sparse point cloud set of teeth at different viewing angles by using a three-dimensional imaging system, wherein the three-dimensional imaging system comprises a main camera and a plurality of light sources; determining a dense three-dimensional point cloud of teeth at each viewing angle according to a sparse point cloud set; and splicing and fusing the dense three-dimensional point clouds at different angles to obtain the three-dimensional data of teeth. The technical problem in the prior art of the high hardware device requirements and computing complexity when three-dimensional data of teeth is collected is solved.

Description

technical field [0001] The present invention relates to the field of computer internet, in particular to a tooth three-dimensional data reconstruction method, device and system. Background technique [0002] Clinically, the three-dimensional data collection of teeth in the oral cavity is divided into two methods: extraoral scanning and intraoral scanning. Extraoral scanning is to scan the plaster model of the patient's dentition with scanning equipment to obtain digital 3D. Intraoral scanning is to extend the scanning equipment into The patient's mouth directly scans and measures the tooth and related soft and hard tissues, and obtains digital 3D in real time. Compared with the extraoral scanning method, the intraoral scanning is truly model-free and digital, convenient and efficient, and has obvious advantages. [0003] At present, the commonly used technologies for intraoral scanning are mainly intraoral reconstruction based on color fringe and reconstruction technology ba...
