Orthodontic arch wire error evaluation method based on bending point curvature and dimension reduction angular distance deviation domain

The invention discloses an orthodontic arch wire error evaluation method based on bending point curvature and a dimensionality reduction angular distance deviation domain, relates to the technical field of orthodontic arch wire bending, and aims at an orthodontic arch wire curve with small z-direction deviation and small curvature between a bending point and an adjacent bending point. An appropriate evaluation method is selected to evaluate an error between an actual orthodontic arch wire and a theoretical orthodontic arch wire. The method is technically characterized by comprising the following steps: importing theoretical orthodontic arch wire curve data and actual orthodontic arch wire curve data; judging whether the end distance error of the orthodontic arch wire curve dental arch, the curvature between adjacent bending points and the z-direction deviation meet the requirements or not; plane transformation of an orthodontic arch wire curve; setting an angular distance deviation domain of an orthodontic ar
