Electronic plane bow method based on multi-view computer vision

Abstract

The invention discloses an electronic plane bow method based on multi-view computer vision. The method comprises the following steps: 1) rigidly connecting markers, wherein the markers are rigidly connected with upper and lower dentitions of a patient; 2) multi-camera video data acquisition: aligning a plurality of cameras to dentition and markers from different angles, and acquiring motion videos of the markers and teeth; 3) motion trail data processing: simplifying an image of the same frame of each camera into a least square optimization problem, and solving to obtain more accurate marker position information; and 4) visualizing the motion trail, converting the motion trail data of the marker, applying the converted motion trail data to the three-dimensional skull lower jawbone model to obtain a reconstructed human head dynamic virtual occlusion action, and rendering and outputting the reconstructed human head dynamic virtual occlusion action to a screen. The method is based on multi-camera computer vision, the moving tracks of the upper and lower jaw joints are captured, and accurate dynamic virtual occlusion simulation is achieved.

Description

technical field [0001] The invention belongs to the field of digital medical treatment, and in particular relates to an electronic face bow method based on multi-eye computer vision, which uses computer vision technology to dynamically simulate the occlusal movement of upper and lower jaws and joints. Background technique [0002] Electronic facebow is a technology that uses digital technology to simulate the movement of human jaws and joints. It has a very good auxiliary effect on the diagnosis of jaw joint diseases, tooth restoration and orthodontics. Traditional facebow technology requires the use of sophisticated mechanical devices, which are complicated to operate, difficult to carry, and limited in expressing information; however, the existing electronic facebow technologies all belong to foreign medical device companies, and most of them use sensor solutions, using optical sensors, motion sensors, etc. To collect jaw movement data, the price of equipment is extremely ...
