WebJan 13, 2024 · To extract the features from an image we can use several common feature detection algorithms. In this post we are going to use two popular methods: Scale Invariant Feature Transform (SIFT), and Oriented FAST and Rotated BRIEF (ORB). For feature matching, we will use the Brute Force matcher and FLANN-based matcher. WebMay 16, 2024 · The solution is to raise the priority of PCL\3rdParty\FLANN .

WebJan 8, 2013 · FLANN stands for Fast Library for Approximate Nearest Neighbors. It contains a collection of algorithms optimized for fast nearest neighbor search in large datasets and for high dimensional features. It works faster than BFMatcher for large datasets. We will see the second example with FLANN based matcher. WebMay 16, 2024 · Maybe there is conflict between OpenCV and PCL because both libraries use flann.
