Data registration method and data registration system

Abstract

The invention discloses a data matching method and a data matching system; the data matching method comprises the following steps: S1, building a local coordinate system for a laser robot, and obtaining a conversion relation between the local coordinate system and a global coordinate system; S2, mounting a locator in a light outlet of the laser robot, scanning the locator so as to obtain the position of the locator in the local coordinate system; S3, obtaining the position of the locator in the global coordinate system according to the conversion relation and the position of the locator in thelocal coordinate system; S4, fixing a denture on the locator and obtaining the position of the denture in the global coordinate system; S5, obtaining the position of a single tooth of the denture inthe global coordinate system; S6, obtaining the position of the single tooth of the denture in the local coordinate system according to the position of a single tooth of the denture in the global coordinate system and the conversion relation. The method and system can improve the obtained position accuracy of the single tooth in the robot coordinate system.

Description

technical field [0001] The invention relates to the field of oral clinical technology, in particular to a data registration method and a data registration system. Background technique [0002] With the continuous improvement of living standards, people have begun to pay more attention to health issues. Teeth are the guardian gods of human health. Having a strong and intact tooth is the guarantee of good health. At present, the prevalence rate of oral cavity First of all, almost everyone will inevitably suffer from dental diseases in their lifetime. The main diseases in the Department of Stomatology are related diseases of teeth and periodontals. In the past ten years, with the increasing attention to oral hygiene, the diversification and marketization of oral medical services have enabled people to choose better medical services. [0003] In recent years, robots have developed at a high speed, and they have been well applied in the clinical field of oral cavity. However, th...

Problems solved by technology

[0003] In recent years, robots have developed at a high speed, and they have been well applied in the clinical field of oral cavity. However, the coordinate system registration in the operation process of medical robots is basically performed by navigation technology, and its accuracy is relatively low. Low
