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.

利用POV-ray光线追踪方法，对植被真实结构模型生成的复杂行播场景下的方向亮温进行快速演算，并针对CLAMP模型中集聚指数，平均叶倾角和叶面积指数，对冠层方向亮温的影响做敏感性分析，得到在不同参数输入条件下DBT的一些规律。

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.

设计和开发了基于机器视觉的麦田除草剂对准喷药控制系统，该系统的视觉子系统首先用过绿的2G-R-B进行植物与土壤背景的分割，其次用改进像素直方图法识别作物中心行，用阈值法识别行间杂草区域，用BP神经网络基于分形和纹理的共同特征识别行内杂草区域，设计并开发了计算机与PLC的通信程序，设计了PLC的运行程序。

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.

该方法分别用直方图法和最大类间方差法二值化图像后，经过8连通区域标记后据其面积属性去除噪声，然后再经一次标记后找出各标记作物的重心点坐标，最后通过Hough变换检测过重心点的直线，即到得到过作物行的中心线，试验结果表明了该方法的有效性。

Already the Mehrgarh people used domesticated wheats and barley and the major cultivated cereal crop was naked six-row barley, a crop derived from two-row barley.
