Multi-Camera Tracking Support for Covert Target Following
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 by recognizing the guards.
Innovation Solution
A tracking support apparatus and system that utilizes multiple cameras to calculate the position of a tracking target, select an appropriate tracker, and transmit distance information to the tracker's terminal, enabling the tracker to maintain a covert approach by displaying or alerting when the distance to the target becomes too close.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a tracker approaches a tracking target to maintain visual contact, then the tracking effectiveness is improved, but the risk of the target noticing the tracker and evading increases
Solution Approach 1:
The system continuously provides feedback to the tracker about their distance to the target through the terminal device. When the distance exceeds the threshold, the system sends a notification to the tracker to approach, and when the distance is within the threshold, it sends a notification to stop approaching. This real-time feedback mechanism enables the tracker to maintain optimal tracking effectiveness while avoiding detection by the target.
Solution Approach 2:
The system introduces an intermediary mechanism (the notification system via terminal device) between the tracker and the target. Instead of the tracker directly sensing their proximity to the target, the system acts as an intermediary that calculates the distance based on position information from multiple cameras and communicates appropriate guidance to the tracker, thereby preventing the target from noticing the tracker's approach.
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 multiple cameras in the system serve multiple functions: they capture video images for tracking, provide position information for distance calculation, and enable the system to monitor multiple areas simultaneously. This multi-functionality justifies the deployment of multiple cameras while managing system complexity, as each camera contributes to several aspects of the tracking operation rather than requiring separate systems for each function.

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.
