The invention relates to a feature point matching method and device in three-dimensional reconstruction, computer equipment and a storage medium, and the method comprises the steps: obtaining a three-dimensional reconstruction image group, carrying out the extraction and matching of SIFT feature points of different view angle images in the image group, and obtaining matched SIFT feature points; according to the matched SIFT feature points, obtaining F matrixes and epipolar lines of different view angle images in the image group; and extracting multi-level feature points of different view angle images in the image group, and matching the extracted feature points according to the F matrix and epipolar constraint to obtain matched feature points in three-dimensional reconstruction. In the whole process, the characteristic that the robustness of SIFT feature points is excellent is fully utilized, an accurate F matrix and an accurate epipolar line are obtained, then multi-level feature points of the image are extr
