Image feature point extraction method and device, electronic equipment and storage medium

The embodiment of the invention provides an image feature point extraction method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining an original image; performing semantic segmentation on the original image to obtain a segmented semantic image; performing grid division on the segmented semantic image to obtain a grid image; performing high-threshold angular point detection on the grid image to obtain first feature point information; and performing secondary corner detection on the grid image according to the first feature point information to obtain feature points. By implementing the embodiment of the invention, the extraction efficiency of the feature points can be improved, the extraction precision of the feature points can be improved, and high-precision feature point extraction can also be realized for areas with unobvious image pixel changes. 本申请实施例提供一种图像的特征点提取方法、装置、电子设备及存储介质，其中，该方法包括：获取原始图像；对所述原始图像进行语义分割，得到分割后的语义图像；对所述分割后的语义图像进行网格划分，得到网格图像；对所述网格图像进行高阈值角
