Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pose detection and tracking technologies face challenges in recognizing objects with rotational symmetry, as images of such objects from different observation positions can be identical, leading to indefinite pose determination.
Innovation Solution
A method and apparatus that adaptively adjust pose information of a virtual object based on the rotational symmetry degree of freedom of a target object, using similarity calculation and clustering analysis on 2D images rendered from different perspectives to determine the symmetry and adjust the pose information accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If pose detection is performed on objects with rotational symmetry using conventional methods, then the detection process is simple, but the pose recognition accuracy deteriorates because images from different observation positions are identical
Solution Approach 1:
The patent introduces an asymmetric virtual object with a unique identifier (such as an arrow or text) that breaks the rotational symmetry of the target object. This asymmetric element provides a reference direction that allows the system to distinguish between different rotational positions, thereby enabling accurate pose recognition without increasing the overall complexity of the detection process
Solution Approach 2:
The patent uses a virtual object as an intermediary element that is superimposed on the target object. This virtual object contains asymmetric features that serve as a mediator to transfer pose information from the symmetric target object to the detection system, allowing accurate pose determination without directly modifying the target object or complicating the detection algorithm
2Ease of operation
If no dedicated processing is performed on objects with rotational symmetry, then the detection process remains simple, but the ability to recognize pose deteriorates
Solution Approach 1:
The patent performs preliminary action by pre-defining a virtual object with asymmetric features and determining its pose information in advance. This virtual object is then superimposed on the target object during detection, allowing the system to maintain simple operation procedures while achieving accurate pose recognition through the pre-prepared asymmetric reference
3Ease of manufacture
If the virtual object is displayed without adjusting pose information based on rotational symmetry, then the display process is simple, but the viewing experience deteriorates due to suboptimal display angles
Solution Approach 1:
The patent implements dynamic adjustment of the virtual object's pose information based on the detected rotational symmetry degree of freedom. The system automatically adapts the display angle and orientation of the virtual object to optimize viewing experience, while maintaining simple display processes through automated calculations that adjust pose parameters in real-time based on the target object's symmetry properties
