针对农业病虫害远程诊断系统中对农作物病虫害图像重构精度要求高的问题,提出基于压缩感知的病虫害图像重构方法。利用压缩感知方法,在传感器数据采集端使用测量矩阵对病虫害图像信号进行观测,测量值通过网络被传输至远程监控端后,再使用正交匹配追踪算法对图像进行重构。为了验证提出的重构方法的有效性,在不同的采样数量下,对病虫害图像的重构进行了仿真。结果表明,该方法能高质量地重构病虫害图像。
針對農業病蟲害遠程診斷繫統中對農作物病蟲害圖像重構精度要求高的問題,提齣基于壓縮感知的病蟲害圖像重構方法。利用壓縮感知方法,在傳感器數據採集耑使用測量矩陣對病蟲害圖像信號進行觀測,測量值通過網絡被傳輸至遠程鑑控耑後,再使用正交匹配追蹤算法對圖像進行重構。為瞭驗證提齣的重構方法的有效性,在不同的採樣數量下,對病蟲害圖像的重構進行瞭倣真。結果錶明,該方法能高質量地重構病蟲害圖像。

Regarding to tackle the problem of demanding high accuracy of reconstructive agricultural plant diseases and insect pests image , a method of diseases and insect pests image reconstruction based on compressive sensing is proposed . Based on the compressive sensing method , it uses measurement matrix to measure the diseases and insect pests image sig-nal on the sensor nodes .After the measured value is transmitted to the remote monitoring by network , orthogonal matc-hing pursuit algorithm is used to reconstruct the image .In order to illustrate the effectiveness of the proposed method , the diseases and insect pests images under different sample quantity are simulated .Experimental results show that the pro-posed method can reconstruct the image with high quality .
