Multi-Camera Tracking Support for Discreet Target Monitoring
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 persons or targets without being noticed, as the targets may evade detection when they sense the tracker's presence.
Innovation Solution
A tracking support system with a position calculating section to determine the target's location, a tracker selecting section to choose the optimal tracker, and an information transmitting section to provide distance information to the tracker, ensuring the target remains unaware of the tracking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a tracker approaches the tracking target closely to maintain visual contact, then tracking accuracy is improved, but the target may notice the tracker and evade detection
Solution Approach 1:
The patent introduces a support system comprising multiple cameras positioned at different locations as intermediaries between the tracker and the tracking target. These cameras capture images from various angles and transmit them to the tracker, enabling the tracker to monitor the target's movements and position without needing to approach closely, thus maintaining tracking accuracy while avoiding detection by the target
Solution Approach 2:
The support system performs multiple functions: it provides visual information to the tracker, calculates distances between the tracker and target, determines relative positions, and supplies map data. This multi-functional system enables the tracker to maintain appropriate distance while still achieving accurate tracking through the integrated information provided by multiple cameras
2Measurement precision
If multiple cameras are deployed to improve tracking support, then tracking accuracy and target awareness reduction are improved, but system complexity increases
Solution Approach 1:
The support system incorporates feedback mechanisms where cameras continuously capture images, the system calculates distances and relative positions based on these images and tracker terminal position information, and then provides this processed information back to the tracker. This automated feedback loop manages the complexity of multiple cameras by systematically processing their outputs and delivering relevant information to the tracker

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.
