Abstract
Traditional video automatic capture and recognition system adopts ZigBee coding and feature extraction method in dynamic environment. Attenuation distortion is produced in the process, which leads to packet loss in video image acquisition and transmission, and the performance of automatic capture is not good. This paper presents a kind of automatic capture system based on Huffman coding and MUX101 switch control. An automatic capture system of video interest area in dynamic environment based on virtual reality. High speed video data is transmitted to AD8021 chip through VXI system bus for feedback resistance control. In order to dynamically extract and capture video features, VCA810 is selected to provide sensor signals to HP sensor through local bus, so as to adjust the video. interest area. The purpose of feature region of interest magnification. The Huffman encoding and the feature extraction of video interest area algorithm are designed as the embedded core parts of the software. The hardware adopts VXI bus technology is adopted in the hardware. The simulation results show that the system has the advantages of high accuracy, low packet loss rate and excellent performance for dynamic video acquisition and interest area analysis.
