The invention relates to a high dynamic video processing system based on a SoC FPGA. The system comprises an image sensor, the SoC FPGA and display equipment, wherein the image sensor is used for collecting and outputting first video data; the SoC FPGA is connected to the image sensor and is used for configuring the image sensor, simultaneously receiving and processing the first video data to formsecond video data and outputting the second video data; and the display equipment is connected to the SoC FPGA and is used for receiving and displaying the second video data. In the invention, a SoCPGA platform is adopted, an integrated level is further increased, the advantages of various chips are performed, and system design difficulty brought by inter-chip data exchange is reduced through astandard bus protocol. Software program exploitation is flexible and convenient and can be transplanted to different hardware platforms. Through a software and hardware cooperation design, hardware system resources can be flexibly used. The FPGA is used for real-time image processing, and calculating performance and real-time performance are effectively increased.

Description

technical field [0001] The invention belongs to the technical field of digital image processing, and in particular relates to a SoC FPGA-based high dynamic video processing system. Background technique [0002] With the development of the times, people have higher and higher requirements for image quality. Under the condition of uneven illumination intensity, low dynamic range (LDR) images have a small dynamic range, and there is often loss of detail in imaging, while high The high dynamic range (HDR) image has a larger dynamic range, which records rich light, shadow and color information in the real scene, and can maximize the restoration of the real scene observed by the human eye. Therefore, high dynamic range Image processing technology has great application value in the fields of film and television special effects, medical imaging, intelligent monitoring, satellite remote sensing, etc. More and more researchers have begun to focus on high dynamic imaging technology. ...

Problems solved by technology

[0004] However, the local contrast of the global mapping is low, and the local details of the image are seriously lost. The global effect of the image cannot be guaranteed by the local mapping, and it is easy to produce halos, and the computational complexity is high.

Moreover, among the processors currently used in image processing technology, serial structure CPUs such as traditional X86 architecture and DSP cannot meet the performance requirements of fast and real-time image processing algorithms. Versatility, flexibility and controllability are relatively poor
