Problems solved by technology

[0002] In recent years, panoramic video has been widely used in many fields due to its large field of view and strong sense of immersion. Panoramic stitching based on multi-channel cameras has high resolution and low image distortion, and has become a hot topic in applications. The video stitching algorithm has a large amount of calculation, and usually cannot realize real-time processing, so the processing process is usually completed on workstations or PCs and other equipment

Embodiment

[0026] Refer to attached figure 1 , a real-time panoramic video splicing display device includes three core parts:

[0027] An FPGA, the model is the ZC7020 chip produced by Xilinx Company, receives the digital video signal sent by the external six-channel camera through LVDS, packs the effective video data and sends it to the multi-core DSP for processing through the SRIO bus, receives the data to be displayed returned by the multi-core DSP, and sends the It is organized into a DVI digital signal containing a video synchronization signal, and the FPGA is connected to the DDR3SDRAM to buffer the video data;

[0028] A multi-core DSP, the multi-core DSP is the TMS320C6678 DSP produced by TI, which receives the video data packaged by the FPGA and sent through the SRIO bus, and performs panoramic video splicing and panoramic roaming; the multi-core DSP is connected to DDR3 SDRAM for the intermediate processing of the splicing algorithm Data cache and cache of input and output da...

Abstract

The invention belongs to the technical field of embedded computer video processing, and especially relates to a real-time panoramic video splicing display device and method. The traditional panoramicvideo splicing display generally collects video data by multi-channel cameras, then processes the collected video data at a workstation or PC (Personal Computer) and is poor in real-time performance.The invention aims to overcome the deficiencies of the traditional panoramic video splicing display in real-time performance, and designs a special embedded device and a corresponding method. The device can receive six channels of video input with different angles, processes the video input and then display the video at any viewing angle in real time. The technical scheme of the invention is to realize real-time video splicing and panoramic roaming on a multi-core DSP, and realizes real-time video data collection, buffering and display by an FPGA (Field Programmable Gate Array).

Description

technical field [0001] The invention belongs to the technical field of embedded computer video processing, in particular to a real-time panoramic video splicing display device and its method Background technique [0002] In recent years, panoramic video has been widely used in many fields due to its large field of view and strong sense of immersion. Panoramic stitching based on multi-channel cameras has high resolution and low image distortion, and has become a hot topic in applications. The video stitching algorithm has a large amount of calculation and usually cannot realize real-time processing, so the processing process is usually completed on workstations or PCs. Contents of the invention [0003] The purpose of the present invention is to overcome the real-time deficiencies of the traditional multi-camera panoramic video mosaic display technology, realize the real-time mosaic of the panoramic video of the six-camera, and at the same time display the video of the spec...
