基于FPGA的以太网图像传输系统

In recent years, with the rapid development of applications such as digital image processing and remote monitoring, there is an increasing demand for real-time transmission of high-quality image data. However, traditional image transmission methods have the problems of data loss and high transmission delay, which limit the reliability and efficiency of real-time image transmission. In order to solve this challenge, this paper designs and implements an FPGA-based Ethernet image transmission system. The system uses the OV5640 camera to acquire images and transmits image data at 640×480 resolution via the UDP protocol. Different from the traditional UDP transmission method, this system introduces an acknowledgment mechanism during data transmission. This acknowledgment mechanism adds a serial number to the data portion of each EtherneEthernet image transmission system based on FPGAt frame to ensurEthernet image transmission system based on FPGAe the integrity and correctness of the data. Through experiments and tests, the feasibility and performance of the system were verified. The results show that the system can stably transmit high-quality 640×480 resolution image data with low transmission delay.
