Beyond ANN: Exploiting Structural Knowledge for Efficient Place Recognition

Stefan Schubert,Peer Neubert,Peter Protzel,Stefan Schubert,Peer Neubert,Peter Protzel

Visual place recognition is the task of recognizing same places of query images in a set of database images. It is important for loop closure detection in SLAM and candidate selection for global localization. Many approaches in the literature perform computationally inefficient full image comparisons between queries and all database images. There is still a lack of suited methods for efficient pla...
