摘要:

为解决航天飞行器采集数据过程由于环境因素影响，噪声干扰严重从而影响图片清晰度与数据高速采集的问题，设计了一款基于双边滤波的高速图像采集系统。该系统FPGA利用HTG8518芯片实现图像数据采集，通过双边滤波算法，降低图像噪点。采用DDR3芯片缓存图像数据，通过RS-422接口与千兆以太网实现与上位机的交互通信。经实验分析验证，该系统设计可以实现数据的高速传输和准确存储，其采集速率约 1.9 Gbps，读取速率约 650 Mbps，图像信噪比增长约5 dB，经多次实验测量后无误码现象发生，可推广应用于军事和航空航天领域图像数据采集。

Abstract:

A high-speed image acquisition system, based on bilateral filtering, has been developed to address the issue of noise interference during spacecraft data acquisition due to environmental factors. The FPGA in the system utilizes HTG8518 chip for image data acquisition and employs bilateral filtering algorithm to reduce image noise. Image data is cached using DDR3 chip, while interactive communication with the host computer is achieved through RS-422 interface and Gigabit Ethernet. Experimental analysis and verification have demonstrated that the system design enables high-speed transmission and accurate storage of data, with an acquisition rate of approximately 1.9 Gbps, a reading rate of about 650 Mbps, a 5 dB increase in image signal-to-noise ratio, and no error occurrences after multiple experimental measurements. This technology can be applied to military and aerospace image data acquisition.
