LHM Definition and Technical Principles
LHM (Large Animatable Human Reconstruction Model) is an open source project developed by the aigc3d team, and its core function is to quickly convert a single 2D human body picture into a 3D model that supports motion adjustment through AI technology. The technological breakthrough is mainly manifested in two dimensions:
- Realization path: Adoption of3D Gaussian SplattingAs a human body representation, this method is efficient in capturing surface details
- Architecture design: combiningMulti-Modal Converter ArchitectureThe system is designed to synchronize geometric structure and texture information.
Compared to traditional 3D modeling methods, LHM's AI-driven solution can compress modeling time to seconds (only 0.2 seconds for A100 graphics cards) while preserving details such as clothing folds and accessories. For the technical implementation, the system analyzes the semantic information of the input image through a deep learning network, predicts the 3D topology of the human body, and finally generates a mesh model that can be edited through differentiable rendering.
