Automatic design method of personalized glasses legs

Abstract

The invention discloses an automatic design method of personalized glasses legs. The automatic design method comprises the following steps: (1) configuring a glasses leg model; (2) moving the glassesleg model to a position where the head end of the glasses leg model is connected with the pile head; (3) deforming the front section part of the glasses leg model to enable the inflection point of theglasses leg model to be matched with the position of the root point on the ear of the three-dimensional face model; and (4) deforming the rear section part of the glasses leg model, so as to enable the tail end point of the glasses leg model to attach to the rear part of the ear of the three-dimensional face model. The glasses legs generated by the automatic design method of the personalized glasses legs are more comfortable and fit to wear, and can effectively hook ears to prevent glasses from falling off.

Description

technical field [0001] The invention relates to an automatic design method for personalized temples. Background technique [0002] CN105842875A discloses a spectacle frame design method based on human face measurement, which is to automatically generate a spectacle frame that fits the user's face according to a three-dimensional face model obtained by scanning the user's face, so as to improve the distance between the spectacle frame and the user's face. Fit and comfort. In this method, the generation process of the temple part of the spectacle frame is mentioned, specifically: the pre-fabricated temple template grid is deformed according to the three-dimensional face feature points and the position of the hinge position (that is, the pile head) to adapt to the user's At the root of the ear, the front joint of the mirror leg moves to a fixed distance from the hinge position, and then the middle joint of the mirror leg moves to the root of the ear, and the tail joint of the ...

Problems solved by technology

But adopting such a method still has the problem that the temples and the wearer's ears cannot be fully adapted. Since the back of the ear of the human body is closer to the inner side than the top of the ear, the tail end of the conventional mirror leg Generally, it also has an inner hook portion that bends toward the inside. The tail end of the mirror leg of the spectacle frame produced by the above patent method does not have an appropriate inward curvature, making it easy to loosen and fall off when worn, and the comfort is poor.
