Embodiment 2

[0072] refer to figure 1 , an FPGA-based Gige Vision interface image transmission implementation method, the overall operation process is:

[0073] a) The camera, embedded image acquisition device and computer are connected to the same local area network, and the system is powered on and initialized;

[0074] b) The upper computer sends the signaling message GVCP, and performs information interaction with the FPGA through the Gigabit Ethernet interface, and negotiates and configures the general boot register and user register in the device;

[0075] c) After the upper computer completes the basic device read and write register operations, it reads the device XML description file in the form of a signaling message;

[0076] d) The host computer software automatically parses the XML file, if the parsing is successful, proceed to the next step, otherwise the software reports an error and returns to step c);

[0077] e) The host computer generates configuration interfaces and tr...
