Insulator recognition based on moments invariant features and Cascade AdaBoost classifier

A method based on moments invariant features and cascade AdaBoost classifier for insulator recognition is put forward to solve the problem of poor performance of insulator recognition. At first, the insulator image is preprocessed by median filtering, dilating, eroding and Otsu thresholding. Then, for the better extraction of moments invariant features, the preprocessed insulator image is tilted correctly based on PCA (Principal Component Analysis). Next, the moments invariant features are extracted and chosen to compose complex classifier in the process of training AdaBoost. Finally, the complex AdaBoost classifiers are combined in a cascade method for insulator recognition. The results of experiments demonstrate that the proposed method can recognize the insulator from complex background in the mountainous area, and it has better robustness, accuracy and validity. © (2013) Trans Tech Publications, Switzerland

Method for high-voltage transmission tower positioning based on linear targets

本发明涉及一种基于线状目标的高压输电塔定位方法，包括以下步骤：利用Hessian矩阵得到每个像素点对应的Hessian矩阵特征向量的方向，该方向即为由该点组成的线状目标的方向；然后利用区域增长的方法提取Hessian矩阵特征向量方向近似的点组成小线段（线状目标）；最后利用统计方法，分别在水平和垂直方向上对小线段进行投票，小线段最集中的区域就是高压输电塔所在位置。本发明检测速度快、检测精度高，能够满足无人机巡检要求
