Embodiment Construction

[0022] The present invention is further described below in conjunction with embodiment.

[0023] In this embodiment, images are collected when the distance between the user's face and the camera is 0.5 meters and 1 meter respectively, the facial contour and eye contour of the collected image are obtained by black and white color tolerance method, and the facial contour is calculated using mathematical methods and the area of ​​the eye contour and the offset value based on the center line of the entire picture; store the collected and calculated data into the standard database; switch each group of gratings to collect the best video grating occlusion angle of the above two sampling distances of different groups of gratings and offset; collect the face image of the current user when using it, obtain the facial contour and eye contour of the collected image through the black and white color tolerance method, and use mathematical methods to calculate the area of ​​the facial contou...

Abstract

The invention discloses methods for distance measurement and offset measurement with a single camera and for realizing naked eye 3D grating adjustment. The method for distance measurement and offset measurement comprises a step of standard data acquisition, a step of current user data acquisition and a step of calculation of distance and offset so as to finally calculate watching distance and horizontal offset of a current user. The method for realizing naked eye 3D grating adjustment is characterized in that distance D and offset H are measured by using the method for distance measurement and offset measurement, each group of gratings is switched to acquire grafting shielding angles and offset of an optimal view of two groups of gratings with different sampling distances, a human eye included angle A is calculated through the formula that A is equal to arcsin(D/H) based on the distance D and the offset H, and based on the value of the human eye included angle A and the data of the optimal view of the two groups of gratings with different sampling distances obtained in the step of standard data acquisition, gratings are selected and the grafting shielding angles and the offset of the gratings are adjusted so as to obtain an optimal visual state. Such a technical scheme is applicable to distance measurement and offset measurement when a single person watches naked-eye 3D hand-held equipment.

Description

technical field [0001] The invention relates to a method for measuring distance and offset through a camera, and a method for realizing naked-eye 3D grating adjustment. Background technique [0002] The light-barrier naked-eye 3D technology is widely used in existing electronic products, because the existing technology is compatible with the LCD liquid crystal technology, so it has great advantages in mass production and cost. [0003] Since the release of the 3D movie "Avatar" a few years ago, various 3D film sources have been released frequently. We know that 3D movies are shot by using two left and right cameras to simulate the left and right eyes of human beings. In the process of watching, we feel the out-of-screen effect of objects flying out of the screen and rushing towards us; feel the in-screen effect of being far away from the screen. The principle is: when we look at an object, the left and right eyes must intersect on the object to form an image. If the object...
