摘要
为保证快速、有效地检测作物行中心线,提出利用基于梯度的随机Hough变换进行作物行中心线检测。针对作物行内植物疏密情况不同分别进行作物行中心线检测分析与研究,发现该方法对不同的作物行内植物疏密情况具有良好的适应性。通过与传统的Hough变换进行对比试验发现,基于梯度的随机Hough变换能够有效提高检测速度。
To ensure spray on crop row effectively,the variable rate spray system based on machine vision needs to detect crop row.In order to ensure rapid and effective detecting the center of crop row,the detection of the crop row with gradi-ent-based random hough transform was proposed.Applying this method in the detection of different plant distribution in row showed a good adaptability.Compared with the method of Hough transform,gradient-based random Hough transform could improve the detection rate effectively.
