Wind generating set cabin feature point matching method and system based on SIFT (Scale Invariant Feature Transform) algorithm

The invention discloses a wind generating set cabin feature point matching method and system based on an SIFT algorithm, and the method comprises the steps: collecting a wind generating set image, transmitting the wind generating set image to a central control room, extracting SIFT key points from the outer contour of the wind generating set image, and carrying out the localization; and carrying out descriptor distribution on the localized SIFT key points to obtain key information, and carrying out feature matching by utilizing the key information to position the outer contour of the wind generating set. According to the method, key feature points are extracted from the images of the cabin of the wind generating set by using the SIFT algorithm, and the feature points are kept invariant under different scales and rotation angles, so that subsequent image matching and recognition are facilitated. 本发明公开了基于SIFT算法的风力发电机组机舱特征点匹配方法及系统，方法包括采集风力发电机组图像，将风力发电机组图像传输至中控室后对风力发电机组图像的外轮廓提取SIFT关键点并本地化，对本地化的SIFT关键点进行描述符分配得到关键信
