摘要
针对不同X光视频设备具有不同技术参数导致无法直接接驳VGA视频的现状,本文在研究建立非标准视频信号特征转换算法库的基础上,提出了一种控制非标准视频AD采样数据读写时序,实现高分辨X光视频对VGA视频的自适应转换设计方案,方便了X光影像的临床研究和教学。
Different manufacturers in the medical X-ray equipment for video output parameters are not unified, and can not be connected to common VGA video adapter. Based on establishing the non-standard video signal conversion algorithm database, this paper proposes a kind of video transformation design based on FPGA. Through the control of non-standard video signal AD sampling data read-write succession in FIFO, this design can complete an X-ray medical video adaptive conversion system that can transform X-ray video signal to real-time VGA video signal, and it can be used for clinical research and teaching.
