Naked eye three-dimensional display device and method through combination of visual fatigue detection

Abstract

The invention relates to a naked eye three-dimensional display device and method through combination of visual fatigue detection. The device mainly is composed of an infrared binocular camera, an eye image analysis unit, an eye space position feedback unit, an eye visual area adjustment unit, a left and right view display and adjustment unit, an eye fatigue detection unit and a video output unit. According to the method, space coordinates of eyes are positioned in real time through adoption of an eyeball tracking technology; eye position movement is tracked in real time and subpixels of corresponding liquid crystal raster image are rearranged through adoption of a programmable logic array technology, thereby changing an optimum viewpoint area, the image crosstalk in an eye watching process is effectively reduced, and the viewing experience of a user is improved. Through application of the technologies, an eye fatigue state of the user in the viewing process is detected, measured and evaluated in real time, and the bad physiological reaction degree of the user is judged, thereby prompting the user to take measures to prevent or mitigate visual fatigue timely.

Description

technical field [0001] The invention belongs to the technical field of eye-tracking naked-eye stereoscopic display, and in particular relates to a naked-eye stereoscopic display device and method combined with visual fatigue detection. Background technique [0002] The biggest feature of autostereoscopic display technology is that users can perceive three-dimensional images without wearing any vision aids. However, autostereoscopic display devices can only form a limited optimal viewpoint in space after the preparation is completed, and users need to move their positions in front of the screen. to find the right viewing angle. During the process of finding the viewing angle, due to the transformation of the viewing area, the two eyes will see the stereoscopic image with crosstalk, thereby affecting the stereoscopic viewing experience of the user. [0003] Tracking autostereoscopic display technology is a kind of autostereoscopic display technology. When determining the spec...

Problems solved by technology

Stereoscopic visual fatigue will cause physical discomfort to users, especially for the elderly and children with imperfect visual mechanisms. Watching 3D display for a long time under the condition of visual fatigue seriously affects the user experience and restricts the development of 3D display technology and related products. popularization of applications
