Web1 jul. 2024 · The HPatches dataset [4] was introduced in form of local patches for benchmarking descriptors and metric learning methods, later extended with images and … WebIn order to compute homography we need point pairs world-camera. If we have a planar marker, we can process an image of it to extract features and then detect those features in the scene to obtain matches. We just need 4 pairs to compute homography using Direct Linear Transform. If I have homography how can I get the camera pose?
