Sensor Data Corridor Designation for Structure Layout Estimation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for fusing multi-sensor data fail to effectively provide accurate layouts of structures, particularly in situations where the layout information is not available, such as for enforcement, security, and military operations.
Innovation Solution
The system analyzes sensor data to identify structural features represented by vectors, generates a score matrix describing their relationships, and designates candidate corridors as either doorways or gaps, ultimately generating a layout of the structures based on these features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multi-sensor data fusion techniques are used to determine structure layouts, then the ability to obtain layout information is improved, but the accuracy and reliability of the determined layouts deteriorates when layout information is not available
Solution Approach 1:
The patent segments the structure layout determination process into distinct phases: identifying structural features from sensor data, representing them as vectors, generating candidate corridors, and designating final corridors. This segmentation allows each phase to be optimized independently, improving overall accuracy even when complete layout information is unavailable.
Solution Approach 2:
The patent transforms structural feature data into a different dimensional representation by creating vectors with multiple attributes (position, orientation, type). This dimensional transformation enables more sophisticated analysis and scoring of candidate corridors, improving measurement precision in the layout determination process.
2Loss of information
If sensor data is analyzed to identify all structural features, then the completeness of layout information is improved, but the complexity of data processing increases
Solution Approach 1:
The patent extracts only the essential structural features from sensor data by representing them as vectors with specific attributes (position, orientation, type). This extraction process filters out redundant information while maintaining completeness of essential layout information, reducing processing complexity.
Solution Approach 2:
The patent changes the parameters of structural feature representation from raw sensor data to standardized vectors with defined attributes. This parameter transformation simplifies subsequent processing steps while preserving all necessary information for complete layout determination.
3Ease of operation
If candidate corridors are designated as doorways or gaps, then the usefulness of layout information for navigation is improved, but the time required to process and designate corridors increases
Solution Approach 1:
The patent performs preliminary classification of candidate corridors into doorways and gaps during the corridor designation phase, rather than during initial data collection. This preliminary action prepares the data for navigation use without significantly increasing total processing time, as the classification uses the already-computed vector relationships.
Solution Approach 2:
The corridor designation process uses the scoring and relationship information already computed during candidate identification, allowing the system to self-service the additional classification task without requiring separate sensor passes or independent processing pipelines, thereby minimizing time loss.
Data Source
AI summary
In particular embodiments, analyzing data includes receiving sensor data generated in response to sensing one or more structures. The structural features of the sensor data are identified. Each structural feature is represented by one or more vectors. A score matrix describing relationships among the vectors is generated. Candidate corridors are identified from at least some of the vectors according to the score matrix. One or more candidate corridors are designated as designated corridors. Each designated corridor comprises an opening defined by at least two structural features. A layout of the structures is generated from the structural features and the designated corridors.
