基于高速DSP深度视频帧内编码的农机导航系统设计

Agricultural Machinery Navigation System Design Based on High-speed DSP and Depth Video Intra Frame Coding

为了解决农机基于电子地图导航系统的抽象性和缺乏沉浸感的缺点,以图像清晰化复原算法为依据,提出了一种基于高速DSP图像处理系统的导航深度视频帧内编码方法,并设计了一种新的农机导航系统,从而实现了导航视频的快速处理,达到了快速精准导航的目的。本次设计的农机导航系统选用高清摄像机作为视频采集装置,使用FPGA作为协同处理器,将深度视频帧内编码数据发送到DSP主处理芯片进行处理,最后将处理得到的结果在VGA接口进行显示。为了验证系统的可行性,以低矮作物的农机导航为测试对象,利用导航系统对作物和障碍物进行了摄像,并对实时获得的视频进行深度视频帧内编码处理,最终得到低矮作物和障碍物的具体标定位置,为农机自主导航线的划定提供了基本依据。

In order to solve the problem of the abstract and lack of immersion of the disadvantages of the electronic map navigation system in agricultural machinery,it proposed a method with clear image restoration algorithm based on a navigation depth video frame image processing system in high speed DSP encoding method based on agricultural machinery.And it designed a new navigation system,so as to achieve fast processing video navigation,to achieve fast and accurate navigation. The design of agricultural machinery navigation system selects high-definition camera as a video capture device by using FPGA as a co processor. The depth of the video frame encoding data was sent to the DSP main processing chip for processing,and the processing result is displayed on the VGA interface. In order to verify the feasibility of the system,the agricultural machinery navigation takes low crop as the test objects by using navigation system of camera on crop and obstacles. Then it obtains real-time video encoding processing depth in the video frame,finally gets the specific position calibration of low crop and obstacles,which provides the basis for the autonomous navigation line of agricultural delineation.
