摘　　要：现有的消化内镜检查通常生成大量高清视频数据,一次检查可能产生几十GB的数据。受限于存储空间问题,传统检查过程中通常依赖于图片记录,无法实现全检查过程视频保存。研制了一种基于区域压缩的消化内镜视频传输系统,提升了设备存储空间的利用率。该系统主要由ZYNQSOC核心处理单元、SFP(Small Form-factor Pluggable)光纤接口及外围电路等组成,构建了基于H.265编码标准的视频柔性区域压缩算法和基于10G以太网的UDP(User Datagram Protocol)传输协议,实现了消化内镜视频的高效压缩与实时传输。试验结果表明,研制的视频处理系统满足实时压缩与传输需求,在满足设定区域图像质量的同时,有效降低了存储需求。Gastrointestinal endoscopy examinations usually generate a large amount of high-definition video data,with a single examination potentially producing dozens of gigabytes(GB)of data.Due to storage limitations,traditional examination procedures often rely on image recording,making it impossible to save the video of the entire examination process.To address this issue,a gastrointestinal endoscopy video transmission system based on regional compression has been developed,which improves the utilization rate of the device's storage space.The system mainly consists of a ZYNQ SOC core processing unit,an SFP optical fiber interface,and peripheral circuits.It incorporates a flexible video regional compression algorithm based on the H.265 encoding standard and a UDP transmission protocol over a 10G Ethernet,enabling efficient compression and real-time transmission of gastrointestinal endoscopy videos.The experimental results demonstrate that the developed video processing system meets the requirements for real-time compression and transmission,ffectively reducing the storage space while ensuring the image quality of the specified regions.
