Hpatches homography estimation
WebThe HPatches is a recent dataset for local patch descriptor evaluation that consists of 116 sequences of 6 images with known homography. The dataset is split into two parts: … 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?
