Embodiment Construction

[0008] The invention provides a multi-channel image acquisition and processing system, which includes an analog CCD camera, a filter network, a video decoding chip, an FPGA chip, a multi-core DSP unit, and a computer. The analog CCD camera collects video data, and the data is processed through the filter network. Filter processing, the data is filtered and processed by the video decoding chip for analog-to-digital conversion, the data converted by multiple groups of video decoding chips is transmitted to the FPGA chip, and the FPGA chip transmits the multi-channel video digital signal to the multi-core DSP unit, and the multi-core DSP unit processes the data and then transferred to the computer. Among them, 2-12 analog CCD cameras can be set according to actual needs, and the analog CCD cameras can collect video from multiple scenes. A single analog CCD camera is filtered by the corresponding filter network, and the single filter network has a corresponding video decoding chip ...

Abstract

A multi-channel image acquisition and processing system comprises simulation CCD cameras, filtering networks, video decoding chips, an FPGA chip, a multi-core DSP unit and a computer, wherein the simulation CCD cameras are used for acquiring video data and carrying out filtering processing of the data through the corresponding filtering networks; data obtained through the filtering processing goes through analog-to-digital conversion through the video decoding chips; data obtained through conversion of the video decoding chips is transmitted to the FPGA chip; the FPGA chip sends a plurality of video digital signals to the multi-core DSP unit; and the multi-core DSP unit processes data and sends processed data to the computer. The system provided by the invention has the advantages that video data acquisition, filtering and decoding of the multiple simulation CCD cameras can be achieved, multiple scene images can be acquired in a parallel manner, and parallel real-time processing and display of the multiple scene images can be achieved through the multi-core characteristic of a DSP.

Description

technical field [0001] The invention relates to a video acquisition and processing system, in particular to a multi-channel image acquisition and processing system.
