| 摘 要： | 以化学防除适期豆田杂草为研究对象,根据条播作物豆田作物行的间距相对固定的位置特征,利用像素直方图法确定作物行的中心行宽并识别行间杂草.通过对几种填充作物行区域的算法进行了大量的研究,得出使用改进的扫描线填充算法分割杂草运行速度最快,避免了重复扫描现象的发生,满足动态实时处理的要求.

| Abstract: | A chemical controlling suitable period weeds in soybean field is simulated based on pixel histogram method to determine centor row width of crop-row and to recognize inter-row weeds.With the relatively position feature of the distance of row crops in soybean field.Several crop-row field filling algorithms have made significant gains in the paper.The opration speed is the most rapid to segment weeds with the puts forward an improved area-filling algorithm,which can avoids repetitious scanning and meets the d... |
