Three-dimensional image dynamic correction evaluation and correction tool aided design method and system

Abstract

The invention relates to a three-dimensional image dynamic correction evaluation and correction tool aided design method, which comprises the following steps of: obtaining three-dimensional scanning information of a human body, obtaining a plurality of two-dimensional images of the human body for identification, calculating pixel values of the two-dimensional images, and synthesizing an original three-dimensional spine curve; and synthesizing the two-dimensional images of the human bodies and the three-dimensional scanning information. And generating a deformed body shape of the human body by using an image deformation prediction body shape correction method. And predicting parameter values of the force application position, the force application direction and the force application magnitude of the corrector on the human body according to the deformed body type by using a spine material characteristic and mechanical model estimation method.

Description

technical field [0001] The invention relates to a three-dimensional image dynamic correction evaluation and orthodontic aid design method and system. Background technique [0002] At present, the traditional plaster casting method is still widely used in the production of scoliosis appliances. However, the different winding methods and tightness of the bandages will cause errors in taking the mould, and the taking time is long, and it is difficult for the patient to maintain a fixed posture, which causes errors in taking the mould. Therefore, plaster casting is time-consuming and laborious, and it is difficult to ensure the correct symmetry of the trunk, front and rear, and the correct production basis for scoliosis orthosis. The follow-up patient's wearing correction function and comfort are also affected, which needs to be further improved. . SUMMARY OF THE INVENTION [0003] The present invention relates to a three-dimensional image dynamic correction evaluation and o...

Problems solved by technology

However, the different winding methods and tightness of the bandage will cause impression errors, and the impression taking time is longer, and it is difficult for the patient to maintain a fixed posture, resulting in impression error

Therefore, taking plaster impressions is time-consuming and laborious, and it is difficult to ensure the correct front-back, left-right, left-right symmetry of the torso. As a result, scoliosis orthodontics cannot obtain the correct basis for making scoliosis orthodontics. The subsequent patients' wearing correction function and comfort are also affected, and further improvement is needed.
