Skeleton Chain Registration to Prevent Animation Clipping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The migration of animation data from one skeleton model to another, especially when the models differ significantly in size or posture, results in noticeable 'clipping through' issues, leading to poor animation display and user experience.
Innovation Solution
An image processing method and apparatus that determines a to-be-registered and a preset skeleton chain, calculates wrist or ankle state information, and finger or toe state information, and displays the target part in a video frame to align and adjust the skeleton points, preventing 'clipping through' and improving display verisimilitude.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If animation data is migrated from one skeleton model to another skeleton model that differs significantly in size or posture, then the animation data can be displayed on different skeleton models, but noticeable 'clipping through' occurs in the display image
Solution Approach 1:
The patent performs preliminary registration and alignment of skeleton points before animation display. By pre-calculating the spatial relationships and establishing correspondence between skeleton points of different models, the system prepares the transformation data in advance, preventing clipping through during actual animation playback.
Solution Approach 2:
The patent replaces traditional manual skeleton alignment with an automated image processing system that uses computer vision and coordinate transformation algorithms. The system automatically identifies, registers, and aligns skeleton points through computational methods, substituting mechanical adjustment processes with digital image processing.
2Measurement precision
If a skeleton model having a relatively large number of skeleton points is used, then more detailed animation can be achieved, but clipping through occurs more frequently leading to poor animation display
Solution Approach 1:
The patent segments the skeleton model into hierarchical groups (body parts, joints, limbs) and processes registration at multiple levels. By dividing the complex skeleton point set into manageable segments and establishing correspondence hierarchically, the system maintains precision for individual points while ensuring overall structural consistency, preventing clipping through.
3Ease of manufacture
If traditional skeleton registration methods are used, then the process is simple, but the verisimilitude of the displayed target part is poor
Solution Approach 1:
The patent introduces an intermediary image processing system that acts as a bridge between the source skeleton model and target skeleton model. This intermediary system uses image analysis and coordinate transformation to establish accurate correspondence relationships, improving verisimilitude while maintaining process simplicity through automated computation.
