Multi-Camera Tracking Support for Covert Distance Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tracking systems, such as those described in Patent Literatures 1 to 6, often fail to support trackers like security guards in effectively tracking suspicious individuals without being noticed, as the tracking targets can evade detection when they sense the guard's presence.
Innovation Solution
A tracking support system utilizing multiple cameras to calculate the position of a tracking target, select an appropriate tracker based on terminal position data, and transmit distance information to the tracker's terminal, enabling covert tracking by maintaining a suitable distance from the target.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a tracker approaches close to the tracking target for effective monitoring, then the monitoring quality is improved, but the tracking target may notice the tracker and evade detection
Solution Approach 1:
The system uses multiple cameras as intermediaries to capture images of the tracking target from different positions. Instead of relying solely on the tracker's direct observation, the cameras serve as mediators that continuously monitor the target and transmit images to the tracker's terminal, allowing monitoring without direct physical proximity
Solution Approach 2:
The patent replaces the mechanical approach of physical close-proximity monitoring with an electronic/image-based system. Multiple cameras capture images that are transmitted to the tracker's terminal, substituting the need for the tracker to physically approach and visually confirm the target's presence
2Measurement precision
If multiple cameras are deployed to improve tracking accuracy, then the position calculation precision is improved, but the device complexity increases
Solution Approach 1:
The system implements feedback by continuously receiving images from multiple cameras, calculating the tracking target's position based on these images, and providing this position information back to the tracker's terminal. This closed-loop feedback mechanism enables accurate position tracking while managing system complexity through automated processing
Solution Approach 2:
The multiple cameras serve multiple functions: they capture images for position calculation, provide continuous monitoring coverage, and transmit data to the tracker's terminal. This multi-functionality justifies the added device complexity by consolidating several roles into a single integrated system
3Reliability
If the tracker maintains a large distance from the tracking target for covert monitoring, then the tracking target is less likely to notice, but the monitoring quality and response time deteriorate
Solution Approach 1:
The system transitions from a single-dimension physical proximity model to a multi-dimensional solution combining remote positioning with image transmission. The tracker remains at a distance for covert operation while receiving real-time position data and images through the communication network, effectively adding the dimension of electronic information transmission

AI summary
A tracking support system includes a position calculating section connected with a plurality of cameras arranged in a predetermined monitoring area to transmit video images imaged by the plurality of cameras and configured to calculate a position of the tracking target based on the video images received from the plurality of cameras; a tracker selecting section configured to select a tracker to be instructed to track the tracking target, based on position information of the terminal received from the terminal and the calculated position of the tracking target; and an information transmitting section configured to transmit information of a distance between the tracking target and the terminal during the tracking of the tracking target to the terminal carried by the selected tracker.
