针对HJ-1卫星提出道路信息的提取方法。将道路根据特征不同分为网状特征和线性特征,提出利用边缘检测+边缘点跟踪与修剪法和SVM分类+过滤细化法进行信息提取,并提出一种提取桥梁信息的方法。试验证明提出的方法能够很好地针对HJ-1卫星提取相关的交通信息。
Aiming at the HJ-1 satellite proposed road information extraction method. According to the characteristics of the road, the road is divided into two kinds of network features and linear features. The method of edge detection + edge point tracking and pruning and SVM classification + filtering and thinning is proposed to extract the information and propose a method of extracting bridge information. Experiments show that the proposed method can extract relevant traffic information well for HJ-1 satellite.
