根据杂草颜色特征,提出了新的图像分割算法,在RGB空间直接将杂草从土壤背帚中分割出来。首先顺序搜索图像中每一个像素点,如果当前像素RGB值中G〉R且G〉嚣,则将该像素值置1(杂草),否则为0(背景),从而完成图像分割。然后采用8邻域消除孤立点,并确定杂草区域位置。利用VisualC++开发了除草机器人杂草识别软件,设计了除草机器人结构模型。试验表明,该分割算法实时性好,可有效识别出杂草,并能够适应户外自然先变化。除草机器人机械臂能够准确定位,完成除草动作。
根據雜草顏色特徵,提齣瞭新的圖像分割算法,在RGB空間直接將雜草從土壤揹帚中分割齣來。首先順序搜索圖像中每一箇像素點,如果噹前像素RGB值中G〉R且G〉囂,則將該像素值置1(雜草),否則為0(揹景),從而完成圖像分割。然後採用8鄰域消除孤立點,併確定雜草區域位置。利用VisualC++開髮瞭除草機器人雜草識彆軟件,設計瞭除草機器人結構模型。試驗錶明,該分割算法實時性好,可有效識彆齣雜草,併能夠適應戶外自然先變化。除草機器人機械臂能夠準確定位,完成除草動作。

A new segmentation algorithm of image was proposed to discriminate weeds from background by using col- or information in RGB space. Firstly, the plant-soil-residue image was analyzed and calculated pixel by pixel, pixel was considered as weed when G〉R and G~〉B and its value was set to 1 ;otherwise,the pixel was considered as back- ground and its value was set to 0. Afterwards,8-neighborhood method was applied to eliminate the isolated points and the locations of weed regions were obtained. The software of weed recognition for weeding robot was developed by means of Visual C+ + and a model of robot structure was designed. Experiments show that this algorithm is ro- bust to the variation of the natural light and takes less time in image processing. The mechanical arm of weeding ro bot could be precisely positioned and carry out weeding activities.
