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.
