WebDec 3, 2024 · We present FlowNet3D++, a deep scene flow estimation network. Inspired by classical methods, FlowNet3D++ incorporates geometric constraints in the form of point-to-plane distance and angular alignment between individual vectors in the flow field, into FlowNet3D. We demonstrate that the addition of these geometric loss terms improves … Webdeep neural network named FlowNet3D that learns scene flow from point clouds in an end-to-end fashion.
