Estimation system and method based on inter-image mutual crosstalk in projection stereoscope visible area

Abstract

The invention discloses an estimation system and method based on inter-image mutual crosstalk in a projection stereoscope visible area. The estimation system comprises a projector, a cylindrical lens screen, a three-dimensional fine-tuning frame mechanical device, a computer and a video camera, wherein the distance between the projector and the cylindrical lens screen is adjusted by the three-dimensional fine-tuning frame mechanical device, the cylindrical lens screen comprises a layer of cylindrical lens grating plate and a diffuse layer, and the projector is connected to the computer which is connected with to the video camera through an image acquisition card. The method provided by the invention is estimated and operated by adopting the estimation system and comprises the following steps of: (1) debugging the estimation system based on the inter-image mutual crosstalk in the projection stereoscope visible area; and (2) calculating the mutual crosstalk among images in the projection stereoscope visible area. By utilizing the video camera as a brightness sensor, the system and the method can individually and accurately judge the inter-image mutual crosstalk degree in the projection stereoscope visible area.

Description

technical field [0001] The invention relates to an evaluation system and method based on crosstalk between images in a projected stereoscopic viewing area. Background technique [0002] Three-dimensional display technology is usually divided into two categories: glasses-type three-dimensional display technology and naked-eye three-dimensional display technology. Glasses-type 3D display technology requires viewers to wear glasses, helmets and other auxiliary equipment, which affects viewing comfort. Glasses-free three-dimensional display technology has made technical improvements to the display source, so that viewers are freed from the shackles of auxiliary equipment and can be watched by multiple people at the same time. Projection 3D display technology is a kind of naked-eye 3D display technology. It is different from contact-type naked-eye 3D display technology. The latter is restricted by the development of liquid crystal panel technology. At present, it is still imposs...

Problems solved by technology

The traditional method is to use a brightness sensor to measure the brightness distribution around the contact display, and use the relative value of the brightness to represent the measurement characteristics of the stereoscopic display. The display characteristics of the viewing area of ​​the monitor cannot use a specific value to evaluate the stereoscopic display effect
