查询词典 pre-arcing

The mathematical models for overall breaking process of circuit breaker are developed, through which the driving mechanism and the arc chamber, the interruption performance and the opening velocity are closely connected, the breaking process under different interrupting conditions are simulated, then the arcing time difference is determined. The interrupting conditions include line charge current, breaker terminal fault current and short line fault current .

SIFT（Scale Invariant Feature Transform） local feature is chosen because of its scale invariance and the property of accurate key-point localization.The Euclidean distance between different SIFT feature vectors is defined as the measure of similarity to get the pre-matched key-point pairs.The affine transform model is used to realize the registration.In order to get the accurate affine transform parameter,the principal of affine transform error is used to get rid of mismatched key-point pairs from the pre-matched pairs.

该方法选取具有良好尺度、旋转不变性以及精确特征点定位能力的SIFT局部特征，使用其特征向量间的欧氏距离作为相似性度量进行特征点匹配，并依据仿射变换误差准则去除奇异匹配特征点对，采用仿射变换的几何模型，实现了遥感图像的快速自动配准。
