Title:
COMPOSITED IMAGE PREPARATION METHOD IN SPECTACLE WEARING SIMULATION
Document Type and Number:
Japanese Patent JP3969842
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To make the scaling value of a side face portrait image easily and accurately fundable in spectacle wearing simulation.
SOLUTION: In this composited image preparation method, the scaling value A of a front face portrait image is obtained as the ratio of an actually measured distance between cornea vertexes to the distance L40 between the cornea vertexes on the front face portrait image. Then, a vertical distance L401 on the front face portrait image between a straight line S300 connecting a right cornea vertex 300 and a left cornea vertex 301 and a chin point 302 and the vertical distance L402 on the side face portrait image corresponding to the distance L401 are obtained. Then, by multiplying the ratio L401/L402 of the vertical distances of the front face image and the side face image by the scaling value A of the front face portrait image, the scaling value B of the side face portrait image is obtained.
