Directional Brightness Temperature of 3D row crop canopy generated by the Clumped Architecture Model of Plants were calculated efficiently and accurately based on the Persistence of Vision Raytracer software. Clumping index, average leaf angle and leaf area index are main parameters of CLAMP model. By analyzing the sensitivity of these parameters to DBT, the changing rules of DBT were found.

The spraying control system aiming at weed based on machine vision was designed and developed. The index of 2G-R-B is used for segmentation and the method of improved pixel lateral histogram is used for extracting the center of crop row,the method of threthold is also used for identificating between-row weed and BP ANN based on fratal and texture is used for identificating in-row weed. PLC correspondence and performing procedure is desi -gned and developed.

To detect the position of crop-rows, a method based on Hough transform and connected component labeling was put forward. First, a true color image of field crops was processed with gray histogram and OSTU respectively. Then the noises in the image were eliminated by means of eight connected component labeling according to their areas. The centroid coordinates of each labeled crop were computed after the second labeling, through which the center line of the crop-row was regressed by Hough transform. Experimental results show that the method is effective.

該方法分別用直方圖法和最大類間方差法二值化圖像后，經過8連通區(qū)域標記后據其面積屬性去除噪聲黄色网站国产精品，然后再經一次標記后找出各標記作物的重心點坐標亚洲sanji在线，最后通過Hough變換檢測過重心點的直線，即到得到過作物行的中心線毛片无限看，試驗結果表明了該方法的有效性美女黄色视频A毛片。
