Multi-Camera Tracker Selection for Covert Suspect 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, especially when the individual becomes aware of the tracking and attempts to evade capture.
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 distance warnings and allowing for tracker substitution when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a tracker approaches a tracking target to maintain visual contact, then the tracking effectiveness is improved, but the target may notice the tracker and attempt to evade
Solution Approach 1:
The patent introduces a support server as an intermediary that receives video images from cameras, calculates tracking target positions, and provides distance information to trackers. This mediator enables indirect tracking support, allowing trackers to maintain appropriate distances while still effectively monitoring targets through centralized position calculation and information distribution.
Solution Approach 2:
The system implements feedback by continuously providing distance information between trackers and tracking targets to the support server, which then adjusts and relays optimal positioning data back to trackers. This closed-loop feedback mechanism enables trackers to maintain effective tracking distances without being noticed by targets.
2Measurement precision
If multiple cameras are deployed to improve tracking coverage, then the tracking precision is improved, but the system complexity increases
Solution Approach 1:
The patent merges the functions of multiple cameras and tracking devices into a centralized support server that performs unified position calculation. By combining camera data processing, position calculation, and tracker coordination into a single central system, the patent achieves high tracking precision through multiple cameras while reducing overall system complexity through centralized management.
Solution Approach 2:
The support server performs multiple functions including receiving video images from cameras, calculating tracking target positions, managing tracker assignments, and providing distance information. This multi-functional centralized system eliminates the need for separate specialized devices for each function, reducing system complexity while maintaining high tracking precision.

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.
