We propose the first fast and certifiable algorithm for the registration of two sets of 3D points in the presence of large amounts of outlier correspondences
The approach allows extending the applicability of Black-Rangarajan duality and Graduated Non-convexity to several spatial perception problems, ranging from mesh registration and shape alignment to pose graph optimization
We propose 3DRegNet, a deep neural network that can solve the scan registration problem by jointly solving the outlier rejection given 3D point correspondences and computing the pose for alignment of the scans
Research on local descriptors for pairwise registration of 3D point clouds is centered on deep learning approaches that succeed in capturing and encoding evidence hidden to hand-engineered descriptors
We propose a feature-metric framework to solve the point cloud registration, and the framework can be trained using a semi-supervised or unsupervised manner
The core of the model is an overlap attention module that enables early information exchange between the point clouds’ latent encodings, in order to infer which of their points are likely to lie in their overlap region
Extracting robust and general 3D local features is key to downstream tasks such as point cloud registration and reconstruction. Existing learning-based local descriptors are either sensitive to rotation transformations, or rely on classical handcrafted features which are neithe...
That MaskNet – augments the ability of existing classical and deep learning-based registration methods to better deal with partial point clouds and outliers, can be used to reject noise, and generalizes to object categories that it was not trained on
While most competing methods get trapped in the local minima caused by non-uniform point sampling, our Fast Gravitational Approach recovers transformations which are closer to the optimal ones, thanks to the boundary conditions defined on masses via the Smooth-Particle Mass funct...
We presented a novel approach to learn local, compact and rotation invariant descriptors end-to-end through a PointNetbased deep neural network using canonicalised patches
We find that the pipeline of our proposed compatibility feature-based 3D correspondence grouping method can be generalized to matching problems for many other data representations, such as 2D images and non-rigid point clouds/meshes, which remains an interesting future research d...
