摘要
根据无人机载视频图像实时采集要求,设计基于i.MX27的视频采集系统;针对TVP5150A视频采集解码芯片和i.MX27视频处理接口要求,分别设计视频解码硬件和软件驱动,编写了视频采集DMA处理程序;实验结果表明,该系统可满足无人机实时视频采集处理要求。
According to the unmanned aerial vehicles video image real--time acquiring requirements, we design a video acquire system based on i. MX27. According to TVPS150A and i. MAX27 interface requirements, we designed the video decoding hardware and software and adopt the video collection DMA processing program algorithm. The flying experiments proved the video data acquiring system performed well and robust.
