Orthodontic arch wire bending region evaluation method based on bending region angle region segmentation

The invention discloses an orthodontic arch wire bending region evaluation method based on bending region angle region segmentation, and relates to the field of orthodontic arch wire bending evaluation. The method comprises the following steps: based on a theoretical orthodontic arch wire curve bending domain space curve and an actual orthodontic arch wire bending domain space curve, evaluating the pose of a space coordinate system in a bending domain; the relative angular region bending error and the total angular region bending error of the actual orthodontic arch wire bending domain space curve are judged by combining the bending point standard degree of the theoretical orthodontic arch wire bending domain space curve and the bending point relative standard degree of the theoretical orthodontic arch wire positive bending domain space curve; and an orthodontic arch wire bending domain evaluation method based on bending domain angle region segmentation is established. According to the method, the bending eff
