This paper proposed an improved Hough transform,in which the accumulator space was treated as another 2-D image,the difference between peaks caused by expected curves and noises in magnified by a local operator.Then histogram was fitted by non-linear least square method,finally the threshold was got to determine the location of expected peaks with higher robustness.The experimental results show that higher accuracy and robustness can be achieved with low requirements about preliminary knowledge.The proposed method can be used in different application,especially for potential real autonomous application.
