Subject Motion Capture for Physical-Makeup-Adaptive Form Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for comparing an individual's form with a model's form fail to account for differences in physical makeup, preventing the individual from achieving the most proficient motion, especially when the physical makeups of the subject and model differ.
Innovation Solution
An information processing apparatus that acquires physical makeup and motion information from multiple viewpoints, generates motion information associated with the subject's physical makeup based on the model's motion, and performs data superimposition, positioning, time synchronization, and deficiency interpolation to facilitate form correction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If skeleton image is superimposed on subject's moving image for form comparison, then form comparison capability is improved, but the subject cannot achieve proficient motion when physical makeups differ
Solution Approach 1:
The patent transforms the model's motion information into subject-adapted motion information by changing parameters based on physical makeup differences. The system calculates subject-specific motion parameters (rotation angles, positions, timing) that account for differences in body dimensions, flexibility, and physical characteristics, allowing the subject to achieve proficient motion adapted to their unique physique rather than forcing identical postures
Solution Approach 2:
The patent introduces subject-adapted motion information as an intermediary between the original model motion information and the subject's actual motion. This intermediary layer processes and transforms the model's motion data into subject-specific guidance, enabling accurate form comparison while accommodating physical differences through calculated adaptation values
2Shape
If subject forcibly takes posture close to model form, then form similarity is improved, but motion proficiency deteriorates due to physical makeup differences
Solution Approach 1:
The patent applies local quality by providing different adaptation levels for different body parts based on individual physical characteristics. Rather than uniformly forcing identical postures, the system calculates subject-specific rotation angles, positions, and timing for each joint and body part, allowing optimal form similarity while maintaining motion proficiency for each local region
3Measurement precision
If multiple imaging apparatuses are used to acquire physical makeup information, then measurement accuracy is improved, but device complexity increases
Solution Approach 1:
The patent creates a digital 3D model (copy) of the subject's physical makeup from multiple imaging data. This virtual model captures essential physical characteristics (dimensions, proportions, body shape) without requiring continuous use of multiple physical imaging apparatuses, reducing device complexity while maintaining measurement accuracy for motion adaptation calculations

AI summary
An information processing apparatus acquires first physical makeup information representing a physical makeup of a first object. The first physical makeup information is information generated based on images obtained by imaging the first object with a plurality of imaging apparatuses in a plurality of directions. The information processing apparatus acquires second physical makeup information representing a physical makeup of a second object and motion information representing motion of a plurality of parts of the second object. The information processing apparatus generates motion information associated with the first physical makeup information based on the second physical makeup information and the motion information relating to the second object.
