Abstract

The present invention discloses a network real-time video collecting device based on FPGA chip and DSP chip development. The device of the invention comprises a video collecting module, a video signal processing module, a network control module, a handshake control module of press button switch and network protocol and an upper machine terminal alternation module. The device realizes the high-speed real-time collection and network transmission to analog video signal / analog television signal or high resolution computer signal. Based on the network handshake protocol between the upper machine and video collecting device which are developed independently on the video collection hardware platform, the specific data in the negotiation package can be flexibly set for controlling the working state of collecting device and realizing the network intelligent control of a plurality of video collecting devices. The device is composed of small-capability FPGA chip and intermediate-performance DSP chip, and can be widely used for the fields of enterprise / family guarding system, real-time video monitoring of operating interface of computer device, visual auxiliary drive of intelligent vehicle, etc.

Description

Network real-time video acquisition device developed based on FPGA chip and DSP chip Technical field: The invention belongs to the technical field of wireless communication, and relates to a network real-time video acquisition device, in particular to a network real-time video acquisition device developed based on an FPGA chip and a DSP chip. Background technique Video acquisition is to solve the problem of obtaining video information. Because the digitized signal is easy to store and process, the video acquisition process generally obtains the analog video signal / analog TV signal CVBS / S-Video (PAL / NTSC system) by the CCD or CMOS camera, and the analog video decoding chip (Decoder) 110 by the analog video decoder Decode and output the digital luminance signal Y conforming to the ITU601 standard, and then perform digital image processing, storage, network transmission and other operations on the digital luminance signal Y. Among them, the field rate of the PAL system is 25...
