【摘要】 针对Hough变换累积矩阵存在的峰值簇拥现象,提出了一种新的Hough变换峰值检测方法。通过对累加器参数空间的分析,考虑到噪声、误差引起的单元累积值的不确定性,在局部最大值周围区域,把每列投票单元看作是随机变量,选用每列的统计方差进行拟合、插值,从而检测到精确的峰值参数。实验结果验证了方法的有效性,与传统方法相比,具有更好的鲁棒性和精确性。更多还原

【Abstract】 In order to deal with the problem of peak expanding of accumulator,a method of peak detection for Hough transform is proposed.By analyzing the distribution of accumulator cells around the local maximum and by considering the uncertainty of voting value of each accumulator cell,the stochastic variance is used for fitting and interpolation.The accurate peak is detected.Experimental results validate the proposed method.Compared with the traditional method,this method is robust and accurate.更多还原
