Title:
SYNTHETIC IMAGE GENERATING METHOD FOR OPTICAL GLASSES WEARING SIMULATION EQUIPMENT
Document Type and Number:
Japanese Patent JPS6376581
Kind Code:
A
Abstract:
PURPOSE:To display an accurate synthesized image of a human image and a glasses frame image by calculating a synthesized magnification by using the coordinates of the cornea vertex position of right and left eyeballs on a screen, and using the inter-pupil distance information of a person, to display accurately a synthesized image of the person's face and the glasses frame. CONSTITUTION:The coordinate XL, YL of the left cornea vertex position of the person on the display screen and that XR, YR right cornea vertex position on the same screen, and the inter-pupil distance IPD value which is the actual measurement value of the person, are inputted to a computer. The angle of inclination of both eyes to the horizontal direction of the screen, and the center positions of both eyes are detected, and the central reference of revolution for revolving amid the image synthesizing is obtained from the middle point between the cornea vertex position coordinates of the left and the right eyes. Thereafter, the synthesizing magnification for fetching the person's image is obtained from the proportion between the IPD measurement value and the distance between the both eyes on the display screen. Since the magnification Kp.(mm/dot) for fetching a frame data is already calculated as a fixed value, the synthesizing magnification (m) for the generation of synthesizing image of the person's image and the frame's image can be obtained by calculation. The generation processing for the synthetic image of the person and the frame is thus executed.
