3D Texture Acquisition Motion Guidance System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for acquiring textures that cover the entire surface of a person are inefficient due to the generation of occlusion areas, requiring specialized movements and being costly or requiring individuals to remain stationary for extended periods.
Innovation Solution
An information processing apparatus and method that generates specific motions for a user to execute, based on the state of texture acquisition, using a motion generation unit and navigation execution unit to guide the user in imaging areas not previously captured, thereby reducing occlusion and enhancing texture coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If 100 or more imaging devices are installed to surround a person for texture acquisition, then texture coverage is improved, but system cost increases
Solution Approach 1:
The system divides texture acquisition into multiple passes, each capturing specific occlusion areas. Instead of using 100+ simultaneous cameras, the system segments the acquisition process into sequential imaging sessions with different camera positions and subject movements, reducing device count while maintaining comprehensive coverage
Solution Approach 2:
The system transitions from a static single-view or multi-view simultaneous capture to a dynamic multi-dimensional approach, moving the camera and/or subject through multiple positions and angles over time. This temporal and spatial dimensionality allows one camera to capture what would otherwise require many simultaneous cameras
2Manufacturing precision
If a person rotates on a turntable for texture acquisition, then texture coverage is improved, but acquisition time increases
Solution Approach 1:
The system performs preliminary identification of occlusion areas through initial imaging, then generates targeted motions specifically designed to expose those areas. This preliminary assessment allows subsequent imaging to focus only on necessary movements, reducing total acquisition time compared to exhaustive turntable rotation
Solution Approach 2:
The system uses the subject's own movements (guided by generated motions) to bring occlusion areas into view, rather than requiring mechanical turntable rotation. The subject actively participates in exposing their own occlusion areas through naturalistic movements, reducing dependency on complex mechanical positioning systems
3Manufacturing precision
If specialized movements are required to suppress occlusion areas, then texture coverage is improved, but ease of operation decreases
Solution Approach 1:
The system continuously monitors texture acquisition status, identifies remaining occlusion areas, and adjusts generated motions in real-time based on this feedback. This closed-loop control ensures that motions are optimized for each subject's specific occlusion patterns, improving coverage while adapting to individual movement capabilities
Solution Approach 2:
The system dynamically adjusts motion parameters (speed, range, type of movement) based on the subject's characteristics and the specific occlusion areas that need to be captured. By changing motion parameters adaptively rather than using fixed specialized movements, the system maintains ease of operation while achieving comprehensive coverage

AI summary
The present disclosure relates to an information processing apparatus, an information processing method, and a program that enable more efficient acquisition of high-quality textures. A motion generation unit generates, on the basis of a state of acquisition of textures that constitute a 3D model of a user, a motion for imaging an area where the textures have not been acquired. Then, a navigation execution unit provides a navigation for making the user execute an action in accordance with the motion generated by the motion generation unit. The present technology can be applied to, for example, an information processing apparatus that performs 3D model generation processing.
