Tracking Assistance Device for Inter-Camera Tracing Error Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing monitoring systems face challenges in efficiently correcting tracing information errors during inter-camera tracing processes, leading to potential loss of tracked individuals, and impose a significant burden on monitoring personnel.
Innovation Solution
A tracking assistance device and method that displays captured images from multiple cameras, allowing monitoring personnel to designate targets, select candidate images with high relevance, and correct tracing information by associating the selected images, thereby reducing the burden and ensuring accurate tracking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the monitoring person manually determines the next display section based on direction of movement, then tracking can be performed, but it takes much time and the monitoring person may lose sight of the person being monitored
Solution Approach 1:
The system performs preliminary action by automatically determining the next display section based on the person's direction of movement before the monitoring person needs to manually determine it. The tracing processing device continuously tracks the person's movement and pre-calculates which display section will show the person next, so when the monitoring person needs to switch sections, the information is already ready, eliminating the time delay of manual determination.
2Extent of automation
If the tracing processing device automatically traces the moving object, then tracking is automated, but errors may occur in inter-camera tracing process causing change of the person to be tracked
Solution Approach 1:
The system implements feedback by allowing the monitoring person to verify and correct the tracing information displayed on the monitoring screen. The tracing processing device provides automatic tracing results, but the monitoring person can review the traced person's information and correct errors if any. This feedback loop ensures that while automation is maintained, the reliability of tracing information is preserved through human verification and correction capability.
3Reliability
If the monitoring person corrects tracing information errors manually, then accuracy can be maintained, but the monitoring burden is significant
Solution Approach 1:
The system enables self-service by providing the monitoring person with a user interface that automatically presents corrected tracing information once errors are detected. The tracing processing device identifies errors in inter-camera tracing and automatically generates correction information, so the monitoring person doesn't need to manually search through complex data or perform complex correction procedures. The system serves itself by automatically preparing correction data, reducing the monitoring burden while maintaining accuracy.

AI summary
A tracking assistance device includes: a target-to-be-tracked setting unit that causes captured images stored in a recorder to be displayed on a monitor and, in response to an input operation performed by a monitoring person to designate a moving object to be tracked, sets the designated moving object as a target to be tracked; a candidates selection unit that selects, as a candidate(s), a moving object(s) highly relevant with the moving object set as the target to be tracked; a candidate image presenting unit that extracts, as a candidate image(s), a captured image(s) in which the candidate moving object(s) is(are) included, and causes the monitor to display the candidate image(s) is(are) such that the monitoring person selects an appropriate candidate image; and a tracing information correction unit that changes the target to be tracked to the moving object associated with the selected candidate image and corrects the tracing information accordingly.
