FPGA-based image data transmission method, system, storage medium and FPGA

Abstract

The invention provides an FPGA-based image data transmission method and system, a storage medium and an FPGA. The method comprises the following steps: the image acquisition instruction sent by an image receiving end is received, the image frames are collected according to the preset frame rate and the image frames are numbered; each image frame is divided into multiple image packets and numbered,and each image packet records the corresponding image frame number and the image packet number; a one-to-one corresponding look-up table is established for each image frame, wherein each data of thelook-up table corresponds to multiple image packet numbers corresponding to each image frame in a one-to-one way, and each data is set as the first value; as for each image frame, the included image packets are sent to the image receiving end; the image receiving packets sent by the image receiving end are received; the look-up table is updated; and the image packets corresponding to the data whose value is the first value in the lookup table are retransmitted. According to the FPGA-based image data transmission method and system, the storage medium and the FPGA, the unreceived image packets can be more conveniently transmitted.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an FPGA-based image data transmission method, system, storage medium and FPGA. Background technique [0002] Among the Ethernet transmission protocols, the most commonly used ones are User Datagram Protocol (UDP for short) and Transmission Control Protocol (Transmission Control Protocol, TCP for short). Among them, the TCP protocol can provide reliable data transmission, but it has obvious disadvantages in real-time transmission; while the UDP protocol has better real-time performance, low overhead and high transmission efficiency, but it usually causes data loss due to unstable network connections. In the case of packet loss, if the receiving end receives high frame rate images, packet loss will often cause display frame loss and frame skipping, which will affect user experience. [0003] For packet loss in the prior art, the data receiving end detects the received data ...
