基于改进Hough变换的农田作物行快速检测算法（Rapid Crop-row Detection Based on Improved Hough Transformation）
作物行检测 机器视觉 直方图投影
2009/8/11
期农田作为研究对象，采集了包含行栽作物和土壤背景的农田图像，针对现有作物行定位方法易受外界干扰和处理速度较慢的不足，提出将投影法和直接Hough变换法相结合检测作物行的算法。采用2G—R—B法和OTSU法将图像二值化，通过快速中值滤波算法去除噪声，再利用垂直直方图投影将图像进行水平条划分获取作物垄平均定位点，最后通过Hough变换检测垄定位点，得到作物行中心线。试验结果表明：基于垂直直方图投影的H...
