Problems solved by technology

[0007] To sum up, the existing intelligent video analysis technology and equipment are mainly dedicated to the detection and tracking of moving objects and the discrimination and alarm of some abnormal situations, without extracting video image features and performing advanced semantic understanding, it is difficult to generate structured description data, thus It is difficult to manage and apply information such as retrieval, browsing, and filtering
Existing equipment and analysis methods do not use digital signal processor DSP and large-scale logic circuit FPGA for video structured description

Abstract

The invention aims to disclose a device and a method for realizing video structural description by using DSP and FPGA. The device and the method realize structural description of input video by using the DSP and the FPGA to organically combine an intelligent image processing technique of the video structural description and a DSP and FPGA-based embedded system, analyze and comprehend video images, generate structural description data, effectively monitor the video and manage the video data, and realize information-based application such as query, browse and retrieval of the video image data and the like; and the device has stable and reliable working performance and wide application range, and can greatly improve the intelligence of the conventional video monitoring system, reduce the manual monitoring cost, realize video monitoring information-based management and fulfill the purpose of the invention.

Description

technical field [0001] The present invention relates to a device and method for realizing structured description of video, in particular to a device and method for realizing structured description of input video by using DSP and FPGA. Background technique [0002] As the importance of video surveillance data in the field of public security becomes more and more prominent, the current video surveillance is mainly based on manual monitoring and manual review of video data to find evidence and clues. With the continuous expansion of surveillance network scale and the rapid growth of video data, it is becoming more and more difficult for manual surveillance and review to meet the growing demand for urban security surveillance. In addition, the existing original video image data is a kind of unstructured data that is difficult to retrieve and query. If you need to find a certain clue or detail through video recording, you must use the method of manually accessing the video clips ...
