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 in effectively tracking targets like suspicious persons without being noticed, especially when the target becomes aware of the tracker's presence, leading to evasion.
Innovation Solution
A tracking support system and apparatus that utilize 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, allowing the tracker to maintain a covert approach without direct line of sight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a tracker directly approaches the tracking target to maintain visual contact, then tracking effectiveness is improved, but the target may notice the tracker and evade
Solution Approach 1:
The system introduces an intermediary support server that mediates between the tracker and the tracking target. The server receives video images from cameras, calculates the tracking target's position, and provides guidance information to the tracker without requiring direct visual contact, thus preventing the target from noticing the tracker.
Solution Approach 2:
The patent replaces the mechanical/physical approach of direct visual tracking with an information-based system. Instead of relying on the tracker's direct observation, the system uses video images captured by cameras, processed by the support server, and transmitted as guidance information to the tracker's terminal, substituting physical presence with digital information transmission.
2Measurement precision
If multiple cameras are deployed to improve tracking accuracy, then position calculation precision is improved, but system complexity increases
Solution Approach 1:
The support server performs multiple functions: receiving video images from multiple cameras, calculating the tracking target's position based on these images, determining the tracker's position, calculating distance and direction information, and transmitting guidance data. This multi-functionality consolidates complex operations into a single centralized system.
Solution Approach 2:
The system automatically processes video images from multiple cameras to calculate positions and generate tracking guidance information without requiring manual intervention. The support server autonomously performs image processing, position calculation, and information transmission, reducing operational complexity despite the multi-camera setup.

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.
