非结构环境下的自适应目标边缘提取方法

深入分析了经典的Canny边缘检测算法,针对其在参数确定的自主能力不高的问题,提出一种新的基于大津法和统计理论的自适应边缘提取方法,通过对一组参数进行了统计优化,自适应地确定边缘检测的全局最优参数。实验结果表明本文提出的非结构环境下目标自适应边缘提取方法能够有效地抑制噪声,自适应地确定最优边缘提取参数,提高了边缘定位精度。最后,通过实验表明,本文提出的方法在环境信息未知月球探测应用中具有较高边缘检测性能。

An in-depth study of algorithm of Canny edge detector is carried out in this paper,and for the sake of improving the ability of parameters selection adaptively,a new method of automatic selection of edge detector parameters based on algorithm of OSTU and statistical theory is presented.The global optimized parameters are determined automatically and adaptively through a optimized method of statistics.Some experiments are carried out and the results show that the method in this paper could reduce the noise a...
