Representing 3D models for alignment and recognition
Thanks to the success of 3D reconstruction algorithms and the development of online tools for computer-aided design (CAD) the number of publicly available 3D models has grown significantly in recent years, and will continue to do so. This thesis investigates representations of 3D models for 3D shape matching, instance-level 2D-3D alignment, and category-level 2D-3D recognition. The geometry of ...
متن کاملSemantic alignment of documents with 3D city models
In urban semantic digital libraries, users need to access heterogeneous types of resources in order to achieve a given task. Contextualisation is known to increase the understanding of documents. With the use of 3D city models, we propose an alignment model that correlates, using the semantic annotations, the different resources of the repository with the different objects contained in the 3D m...
متن کاملAn Area-Based Alignment Method for 3D Urban Models
The alignment method refers to the idea of superposing a model onto an image. The problem is separated in two parts, i) first find a possible transformation of the model on the image ii) then validate this transformation by aligning the model onto the image. We propose an extension of the traditional alignment method in order to deal with complex objects sustained by projective mappings. Much o...
متن کاملIndoor-Outdoor 3D Reconstruction Alignment
Structure-from-Motion can achieve accurate reconstructions of urban scenes. However, reconstructing the inside and the outside of a building into a single model is very challenging due to the lack of visual overlap and the change of lighting conditions between the two scenes. We propose a solution to align disconnected indoor and outdoor models of the same building into a single 3D model. Our a...
متن کاملJoin Tensors: On 3D-to-3D Alignment of Dynamic Sets
This paper introduces a family of 4 4 4 tensors, referred to as “join tensors” or Jtensors for short, which perform “3D to 3D” alignment between coordinate systems of sets of dynamic 3D points. 3D Configurations of points are obtained by a 3D measuring device (such as a structured light or laser range sensor, or a stereo rig) at times t1; t2; t3 from different viewing positions in addition to t...
