Design and Implementation of Video Acquiring System Based on TW9912 in Unmanned Aerial Vehicles

According to the requirements of UAV real-time video image acquisition system,an embedded video acquisition and processing system is designed.The CSI can only process progressive digital video data while the analog camera can only process interlaced video data input.To solve the analog camera and CSI interface problems,the de-interlace digital data processing is completed by using TW9912.The experimental results show that the program processing method can effectively solve the past method of using image processing algorithm software treatment.So the video data compression system performs well in the flying experiment,and the flying experiment proves the correction and robustness of the system.
