  • Patent number: 11816795
    Abstract: The photo-video based spatial-temporal volumetric capture system more efficiently, produces high frame rate and high resolution 4D dynamic human videos, without a need for 2 separate 3D and 4D scanner systems, by combining a set of high frame rate machine vision video cameras with a set of high resolution photography cameras. It reduces a need for manual CG works, by temporally up-sampling shape and texture resolution of 4D scanned video data from a temporally sparse set of higher resolution 3D scanned keyframes that are reconstructed both by using machine vision cameras and photography cameras. Unlike typical performance capture system that uses single static template model at initialization (e.g. A or pose), the photo-video based spatial-temporal volumetric capture system stores multiple keyframes of high resolution 3D template models for robust and dynamic shape and texture refinement of 4D scanned video sequence.

  • Publication number: 20230230304
    Abstract: Mesh-tracking based dynamic 4D modeling for machine learning deformation training includes: using a volumetric capture system for high-quality 4D scanning, using mesh-tracking to establish temporal correspondences across a 4D scanned human face and full-body mesh sequence, using mesh registration to establish spatial correspondences between a 4D scanned human face and full-body mesh and a 3D CG physical simulator, and training surface deformation as a delta from the physical simulator using machine learning. The deformation for natural animation is able to be predicted and synthesized using the standard MoCAP animation workflow. Machine learning based deformation synthesis and animation using standard MoCAP animation workflow includes using single-view or multi-view 2D videos of MoCAP actors as input, solving 3D model parameters (3D solving) for animation (deformation not included), and given 3D model parameters solved by 3D solving, predicting 4D surface deformation from ML training.

  • Publication number: 20220319114
    Abstract: An integrated photo-video volumetric capture system for 3D/4D scanning acquires 3D scans and 4D scans by acquiring images and videos simultaneously. The volumetric capture system for high-quality 4D scanning and mesh-tracking is used to establish topology correspondences across a 4D scanned mesh sequence for generating corrective shapes which will be used in shape interpolation and skeleton driven deformation. The volumetric capture system aids mesh-tracking for maintaining mesh registration (topology consistency) along with ease of extreme pose modeling. Major upper body and lower body joints are able to be identified that are important for generating deformation and capturing the same using a wide range of motion for all movement types across all joint categories. By using the volumetric capture system and mesh tracking, the topology changes are tracked. Each pose captured will have the same topology which makes blending between multiple poses easier and more accurate.
