Tracking type multi-angle three-dimensional display image quality improving method

Abstract

The invention discloses a tracking type multi-angle three-dimensional display image quality improving method, which comprises the steps of: obtaining eye images through an image acquiring device and transmitting the eye images to an image processing device, determining positions of eyes by the image processing device according to an iteration algorithm, respectively figuring an included angle theta L between the position of the left eye and the normal of a display and an included angle theta R between the position of the right eye and the normal of the display, transmitting position information of the eyes to an image synthesizing device by the image processing device; and firstly reading a three-dimensional display parameter by the image synthesizing device, and judging the states of the eyes by the image synthesizing device according to the position information of the eyes, and filling corresponding view angle images in corresponding pixel points. According to the invention, a three-dimensional effect can be obtained on a multi-angle three-dimensional screen by only using two two-dimensional three-dimensional images, the hardware cost can be greatly lowered, and by matching with a face tracking system, the three-dimensional effect can be shown in a viewing angle at any moment.

Description

technical field [0001] The invention relates to the field of multi-view stereo display, in particular to a method for improving the image quality of a tracking multi-view stereo display. Background technique [0002] Traditionally, N different stereoscopic images are generated on a stereoscopic display screen with N viewing angles to present a three-dimensional [0003] Effect, the method is to use two 2D images to synthesize a depth map, and then use one of the 2D images and the depth map to cooperate with the depth image rendering method to generate N images of different perspectives, and then fill in the different images in order. to the position corresponding to the viewing angle of the human eye. [0004] When the number of viewing angles of the stereoscopic display screen is more, the number of frames needed to be calculated will be more. When the video is played, at least 30 images must be presented per second. If the number of viewing angles is N, it is necessary to...

[0004] When the number of viewing angles of the stereoscopic display screen is more, the number of frames needed to be calculated will be more. When the video is played, at least 30 images must be presented per second. If the number of viewing angles is N, it is necessary to calculate the images of 30*N pictures. At present, the multi-view stereo screen has at least 8 viewing angles, so it is necessary to calculate 30*8=240 pictures in one second, and then fill in the corresponding pixels. To achieve real-time conversion, the required hardware The cost of resources is extremely high. In addition, because each picture is different, plus the stereoscopic display will change the light, so that when the human eye sees the picture, it will feel the resolution, color cast, and brightness reduction in the human brain. And when the number of viewing angles of the stereoscopic screen increases, the perceived resolution, color shift, and brightness will be worse, causing inconvenience in use
