Flow Line Synthesis Device for Trajectory Overlap Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for acquiring and associating flow line information are limited, as they restrict the type of information that can be associated with the flow line, and methods for interpolating interrupted flow lines only connect additional information within the flow line, thereby limiting the added value of the information.
Innovation Solution
A flow line synthesis device and method that acquire first and second flow line information using different methods, determine overlapping trajectories, and generate third flow line information by synthesizing the two, where the overlapping satisfies a predetermined condition, thereby enhancing the added value of the flow line information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If flow line information from different methods is synthesized, then the added value and completeness of flow line information is enhanced, but the complexity of the system increases
Solution Approach 1:
The patent combines multiple flow line information sources (first flow line information from one method and second flow line information from another method) into synthesized flow line information. The synthesizing unit merges these different data sources to create more complete and valuable flow line representations, directly addressing the information loss problem while managing complexity through systematic integration.
Solution Approach 2:
The synthesized flow line information serves multiple purposes: it can be used for trajectory analysis, interruption detection, and various applications requiring comprehensive flow line data. The system handles multiple types of flow line information simultaneously, making the synthesis mechanism universally applicable to different information sources and use cases.
2Measurement precision
If multiple flow line information sources are combined, then the accuracy and completeness of trajectory representation is improved, but the difficulty of determining overlapping trajectories increases
Solution Approach 1:
The determination unit acts as an intermediary that processes and compares multiple flow line information sources to identify overlapping trajectories. It mediates between different measurement methods by establishing correspondence relationships, using likelihood calculations and identification information to bridge the gap between different trajectory representations and determine their overlaps systematically.
Solution Approach 2:
The system changes parameters such as likelihood thresholds and identification information criteria to control the overlapping determination process. By adjusting these parameters, the system can flexibly manage the detection difficulty while maintaining accurate trajectory representation, allowing optimization based on specific application requirements.

AI summary
The present invention provides a technique for enhancing the added value of flow line information. The flow line combining device is provided with: an acquisition unit for acquiring first flow line information indicating a trail of positions determined by using a first method and second flow line information indicating a trail of positions determined by using a second method which is different from the first method; a determination unit for assessing overlap in the trails respectively indicated by the acquired first flow line information and the second flow line information; and a combining unit for generating third flow line information which combines the first flow line information and second flow line information if the trail overlap assessed by the determination unit meets a predetermined condition.
