Abstract

The invention discloses an image processing apparatus based on a field-programmable gate array (FPGA). The image processing apparatus comprises an image processing board card and a computer host part, wherein the image processing board card is used for collecting, processing and storing image signals, and transmitting original image data and characteristic value data to the computer host part in a packet manner; the computer host part is used for receiving and analyzing a data packet sent by the image processing board card, and providing an image classifier and a user interface software. And the image processing board card is mounted on the main board of the computer host part by means of peripheral component interconnect-express (PCIe) bus expansion. The image processing apparatus based on FPGA is low in circuit scale, high in hardware integrity, as well as excellent in timeliness and expandability.
