Abstract

The invention discloses a naked eye three-dimensional image synthetic system capable of retarding dead angles, comprising a depth image generation unit, a depth image-based rendering unit, a storage, an anti-parallax image device, a naked eye screen pixel synthesizer and a display screen, wherein the input end of the anti-parallax image device is respectively connected with the output ends of the depth image generation unit and the depth image-based rendering unit; the output end of the anti-parallax image device is connected with the input end of the naked eye screen pixel synthesizer; the output end of the naked eye screen pixel synthesizer is connected with the display screen. Anti-parallax images are generated by the anti-parallax image device, used for replacing or inserted into multi-view images generated by the depth image-based rendering unit, the cavities of the multi-view images are filled, the synthesized final multi-view parallax becomes small, the continuous feeling is produced by people, more comfortable multi-view images are obtained, the cavities of the generated images are fewer, the range of the cavities is small, the workload and time for repair are reduced, and the multi-view images which are closer to actual images are obtained.

Description

technical field [0001] The invention relates to the technical field of multi-view and three-dimensional image synthesis, in particular to a naked-eye stereoscopic image synthesis system capable of alleviating blind spots and a synthesis method thereof. Background technique [0002] Following high-definition television, stereoscopic television (3DTV) will become the development direction of the next-generation television technology. The traditional stereoscopic video is obtained by fixing the left and right cameras in the scene to simulate the eyes of people from two different angles. This results in the need to transmit two channels of video when transmitting programs. In order to reduce data transmission, both the joint video team JVT and the European ATTEST project suggest adopting the data format of "video + depth". In this way, the left and right videos can be synthesized from the middle video and its corresponding depth image (depth iamge), which is the depth image ba...
