| 摘 要： | 依据霍夫（Hough）变换原理,给出了多条直线检测的算法,分析了基于霍夫变换（HT）检测多条直线的特点,即直线—峰值对应性,检测直线不确定性（针对斜率大于0的情况）,累加器A的值与待测直线段长度的关系,带噪声多条准直线的参数空间峰值特征,倾角为90°的直线段参数空间峰值特征,并有针对性的提出了改进方法。提出了依据峰值自动搜索填充范围的算法,实现了峰值的搜索,并通过马铃薯作物的行检测验证了该方法的有效性。

| Abstract: | In this paper,the multi-line detection arithmetic and its characteristics have been described based on Hough transformation principle.The characteristics include the corresponding of line & peak value,the uncertainty of multi-line detection for above-zero slope lines,the relationship between accumulator value and detected line-length,the peak value characteristics of parameter space for the multi similar lines with noise and the peak value characteristics of parameter space for the obliquity which is just 9... |
