Abstract

The invention discloses a 3D (Three Dimensional) digital video signal processing method and a device thereof. The method comprises the following steps of: connecting an external 3D digital video signal source and receiving; detecting a format of the signal; receiving and storing the signal; processing the spatial domain of the signal; processing the time domain of the signal, outputting the signal, and the like. The device comprises a field programmable gate array (FPGA) chip, an HDMI1.4A receiving circuit, a micro processing unit (MCU), an infrared 3D signal synchronous sending circuit, an image storage, a 3D video image simulation sender and a 3D video digital sender. The invention provides an effective path for the display of a 3D digital video, which makes the traditional television in the family of a consumer show a 3S image without modification.

Description

technical field [0001] The invention relates to the technical field of 3D display, in particular to a 3D digital video signal processing method and device thereof. Background technique [0002] Stereoscopic display technology is currently a cutting-edge research topic in the field of display. It is the main supporting link of virtual reality technology and a key research direction in the information field. Its core is to use computer graphics, image processing and optical technology to convert raw data into graphics or The theory, method and technology that image parameters are displayed three-dimensionally on the screen and can be processed interactively. It involves many technical fields such as computer graphics, image processing, computer-aided design, computer vision and human-computer interaction, sensors, and automated servo systems. 3D virtual display is realized through the presence of stereo vision, and has become one of the research hotspots in various countries ...
