Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current computing systems for robot interaction in environments like warehousing struggle to accurately detect objects and plan motion due to limitations in identifying multiple potential object recognition templates and handling unmatched regions, leading to potential errors in robot-object interaction.
Innovation Solution
A method involving a computing system that processes image information from a camera to identify primary and additional detection hypotheses, generating a safety volume list that includes candidate regions and unmatched regions, to enhance the robustness of object detection and motion planning for robot interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the system selects only a primary detection hypothesis with the highest confidence value, then the decision-making process is simplified and faster, but the accuracy and robustness of object detection deteriorates due to inability to handle ambiguous cases and unmatched regions
Solution Approach 1:
The system performs partial detection by identifying a primary detection hypothesis with the highest confidence value for immediate action, while simultaneously performing excessive detection by identifying secondary detection hypotheses and generating safety volumes for ambiguous cases. This allows the system to make quick decisions when confident while preparing fallback options when uncertain, resolving the contradiction between speed and accuracy.
Solution Approach 2:
The system generates safety volumes around the primary candidate region based on secondary detection hypotheses before actual robot interaction occurs. This beforehand cushioning creates a protective buffer zone that accounts for detection uncertainties and unmatched regions, allowing the system to maintain fast decision-making while compensating for potential accuracy issues through pre-computed safety margins.
2Reliability
If the system identifies multiple matching object recognition templates and generates safety volume lists, then the robustness of object detection improves, but the computational complexity and processing time increase
Solution Approach 1:
The system applies local quality by generating safety volumes only for specific regions where detection uncertainty exists (unmatched regions adjacent to primary candidate regions). Instead of uniformly processing the entire image with multiple templates, the system focuses computational resources locally on ambiguous areas, improving detection robustness while controlling overall computational complexity.
Solution Approach 2:
The detection process is segmented into distinct stages: primary detection hypothesis identification, secondary hypothesis identification, and safety volume generation. This segmentation allows the system to handle multiple matching templates in a structured manner, processing only relevant regions at each stage rather than all templates simultaneously, thereby reducing computational complexity while maintaining reliability.
3Measurement precision
If the system generates safety volumes for unmatched regions, then the completeness of object detection improves, but the false positive rate may increase due to including uncertain regions
Solution Approach 1:
The safety volume acts as an intermediary between the primary candidate region and the unmatched region. It is generated based on secondary detection hypotheses and serves as a buffer zone that requires further verification before final detection confirmation. This intermediary structure allows the system to maintain detection completeness while providing a mechanism to filter out false positives through additional validation steps.
Solution Approach 2:
The system performs preliminary anti-action by generating safety volumes that anticipate potential false positives in unmatched regions. These safety volumes are designed to be conservative and require additional verification, effectively pre-combating false positive errors before they can affect the final detection result. This approach maintains completeness while actively working to prevent false positives.

AI summary
A method and computing system for performing the method are presented. The method may include receiving image information representing an object; identifying a set of one or more matching object recognition templates associated with a set of one or more detection hypotheses. The method may further include selecting a primary detection hypothesis associated with a matching object recognition template; generating a primary candidate region based on the matching object recognition template; determining at least one of: (i) whether the set of one or more matching object recognition templates has a subset of one or more remaining matching templates, or (ii) whether the image information has a portion representing an unmatched region; and generating a safety volume list based on at least one of: (i) the unmatched region, or (ii) one or more additional candidate regions that are generated based on the subset of one or more remaining matching templates.
