Embodiment Construction

[0022] The present invention will be further described below in conjunction with drawings and embodiments. The system of the present invention carries out the three-dimensional transformation to the plane video automatically, such as figure 1 As shown, it mainly includes an input module, a sampling module, a calculation module, a storage module and an output module.

[0023] The basic operation process of the system is: the input analog VGA video signal is firstly converted by AD9883 chip to obtain digital RGB signal flow, the sampling module samples the RGB signal flow, and converts the sampling data of each frame into brightness information The ping-pong storage mechanism is used to store in the storage module (frame buffer on-chip RAM), and the calculation module calculates by comparing the sampling data of the previous frame in the storage module with the data of the current frame to obtain the depth information of the plane image, and then according to the current frame. ...

Abstract

The invention designs a system for full-automatically converting a planar video into a stereoscopic video based on FPGA, which mainly comprises an input module, a control module, a sampling module, a calculation module and an output module. The calculation module acquires depth information of the current image according to the sampling image information and the current image information stored in a memory module so as to acquire a depth graph, and then acquires eight images with different visual angles from the depth graph and a plane graph by utilizing a DIBR algorithm, and finally fuses the eight images with different visual angles to form a stereo image according to display specification. In the process of converting the planer video into the stereoscopic video, the system of the invention uses FPGA hardware without involvement of a computer, thus greatly reducing cost, and the high integration of an FPGA chip leads the system to have the characteristics of portability and dexterity. The system can automatically complete video conversion without manual involvement, thus saving a large amount of manpower and time, and improving the conversion efficiency of the planer video to the stereoscopic video.

Description

technical field [0001] The invention relates to the field of converting plane video to stereo video, in particular to a fully automatic plane video converting system based on FPGA hardware. Background technique [0002] Three-dimensional images and displays are an important form of expression for future information systems. Three-dimensional images and displays have distinct layers and bright colors, have a strong visual impact, and can leave a deep impression on people. And the characteristics that video does not have, so it has broad application prospects in fields such as television, inspection, medical treatment, media, and electronic games. At present, stereoscopic display is rapidly applied to various fields of people's life at an astonishing speed. [0003] We will use technologies such as computer vision to convert plane media resources into media resources containing three-dimensional information, which is called plane-to-stereo technology. The planar video to ste...
