Abstract

The invention discloses a naked eye 3D display method and device, and the method comprises the steps: calling a camera, and obtaining the specific coordinates of a viewer in a visual range of the camera; calculating an effective display range according to the specific 3D coordinate positions of the left eye and the right eye of a viewer, and forming a depth map according to the obtained coordinate visual image; obtaining 3D coordinates of the left eye and the right eye according to the formed depth map, and forming an interlaced multi-view image; according to an effective display range calculated according to the obtained interlaced multi-view image, adjusting an image arrangement coordinate system, adjusting a to-be-displayed position of a camera display screen, and respectively obtaining effective visual images of the left eye and the right eye. According to the method, the viewpoint conversion precision is high, the distortion is small, the phenomena of image artifacts, jitter and the like of naked eye 3D display are greatly reduced, the cost is lower, the application value is higher, and the viewpoint conversion is sent to a naked eye 3D display so as to realize naked eye 3D display; the conversion of naked eye 3D viewpoints is efficiently achieved, and few resources are occupied.

Description

technical field [0001] The invention relates to the technical field of naked-eye 3D display, in particular to a naked-eye 3D display method and a display device. Background technique [0002] With the gradual maturity and development of 3D display technology, the application scenarios of naked-eye 3D technology are becoming more and more extensive. Different from traditional two-dimensional display technology, naked-eye 3D display has the advantages of realism, three-dimensionality, no need to wear special glasses, etc., and can effectively avoid adverse reactions such as nausea, dizziness, and visual fatigue caused by immersive experience. It is optimistic and sought after in this display application field. Glasses-free 3D display technology means that without any tools, the left and right eyes can see two different pictures with parallax on the display screen, and reflect them to the brain to produce a three-dimensional effect. Glasses-free 3D display technology also mak...
