An equivariant convolution-based feature detection algorithm for matching unmanned aerial vehicles images with large rotations

Jiachuang Zhang, Hongguang Li, Song WANG, Rong Li et autres

Image matching is critical for Unmanned Aerial Vehicle (UAV) mapping and geolocation. However, traditional methods struggle with weak textures, and most deep learning models often lack rotation equivariance, causing performance degradation under large-angle changes. To address this, this paper proposes the Equivariant …
