Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image generating technologies for multi-body objects fail to produce natural images when strong forces or accelerations are applied, leading to unnatural rendering due to misalignment of joints in iterative calculations.
Innovation Solution
An image generating device and method that iteratively calculates motion based on physical constraints, acquires parent-child information to correct the position of child elements relative to parent elements, and generates images based on these corrections, ensuring joint positions satisfy predetermined conditions, even under strong forces or accelerations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If iterative calculation method is used to calculate motion of multi-body object, then interaction among elements is taken into consideration, but generated image becomes unnatural when strong force or acceleration is applied
Solution Approach 1:
The patent implements a feedback mechanism where joint positions are monitored during iterative calculation, and corrections are applied when misalignment exceeds a threshold. The correcting unit adjusts child element positions based on parent element positions, creating a closed-loop control system that maintains joint alignment accuracy even under strong forces or accelerations.
Solution Approach 2:
The patent performs preliminary establishment of parent-child relationships between elements before the iterative calculation begins. This preliminary structuring allows the system to pre-identify which elements need to maintain positional relationships, enabling more efficient and accurate correction during the calculation process without requiring extensive iterative adjustments.
2Reliability
If iterative calculation is performed to consider interaction among elements, then physical constraint conditions are satisfied, but calculation time increases
Solution Approach 1:
The patent performs preliminary establishment of parent-child relationships and identification of constraint conditions before the main iterative calculation. This preprocessing step organizes the calculation structure in advance, allowing the iterative process to focus only on necessary adjustments rather than evaluating all possible constraints from scratch each iteration, thereby reducing overall calculation time.
Solution Approach 2:
The patent applies correction only to specific child elements whose joint positions deviate from thresholds, rather than uniformly adjusting all elements in the multi-body system. This localized correction approach maintains physical constraint satisfaction while minimizing unnecessary calculations and reducing overall computation time.
3Reliability
If position correction is applied to maintain joint alignment, then image naturalness is improved, but device complexity increases
Solution Approach 1:
The patent segments the multi-body object into parent elements and child elements with hierarchical relationships. This segmentation allows the correction mechanism to operate independently on child elements based on their parent's position, simplifying the overall correction logic compared to a holistic approach that would require coordinating all elements simultaneously.
Solution Approach 2:
The patent performs preliminary establishment of parent-child relationships and pre-definition of correction thresholds before the iterative calculation begins. This preliminary structuring simplifies the main calculation loop by having all correction rules and relationships pre-configured, reducing the complexity of real-time decision-making during iteration.
