The invention discloses a method for designing a glasses
frame based on facial three-dimensional measurement, comprising: (1), acquiring a three-dimensional grid model of a facial area and a three-dimensional facial feature
point set; (2), selecting a
glasses type and setting glasses generation parameters; (3), acquiring two complete lens grids composed of a plurality of rows of curves and a plurality of columns of curves; (4), acquiring two complete rim grids; (5), generating a complete
nose bridge grid between the rim grids; (6), moving points, closest to the
nose, from
nose pads to the surface of the nose, and after iteration, updating a position of an apex of the nose pad grid to the rim grids to obtain a combined lens frame grid; (7), generating two hinge positions of a hinge and legs to finish the designing of the glasses frame. The shapes of the nose pads are optimized automatically according to the nose shape of a user, fitting degree is high, and
adaptation to
asymmetry of the face is achieved; the length and orientation of the legs are adjusted automatically according to positions of ears, providing comfort of wearing and rarity of sliding; manufacture cost is reduced greatly.
