Monitoring Camera Tracking via Mobile Position and Candidate Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing monitoring systems fail to effectively track a moving user of a mobile communication terminal using a monitoring camera, as the camera cannot necessarily include the user in the photographed image when the user is in motion.
Innovation Solution
A monitoring system that includes a mobile terminal and a management device, which estimates the presence of tracking by a security guard, extracts moving objects from camera images as tracking candidates, and highlights these candidates for selection by an operator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the camera is controlled to the position acquired from the mobile communication terminal and photographing is performed, then the user's position information can be transmitted to the monitoring camera, but the photographed image cannot necessarily include the user when the user is moving
Solution Approach 1:
The patent introduces a monitoring center as an intermediary between the mobile terminal and the monitoring camera. The monitoring center receives position information from the mobile terminal, determines appropriate camera control actions, and manages the tracking process. This intermediary coordinates multiple cameras and handles the complexity of tracking moving targets, resolving the contradiction between position accuracy and tracking reliability.
Solution Approach 2:
The system dynamically adjusts camera control based on the moving state of the target. When a user is detected as moving, the system continuously updates position information and adjusts camera positioning in real-time. This dynamic adaptation allows the system to maintain reliable tracking of moving users by constantly responding to position changes.
2Productivity
If the camera is controlled based on position information of the mobile terminal, then the system can transmit user position information, but the system complexity increases when multiple cameras and tracking modes are involved
Solution Approach 1:
The patent divides the monitoring system into distinct functional modules: mobile terminal for position acquisition, monitoring center for decision-making, and multiple monitoring cameras for image capture. This segmentation allows each component to perform its specific function efficiently, improving overall monitoring productivity while managing system complexity through modular design.
Solution Approach 2:
The system merges multiple cameras under unified control from the monitoring center, which consolidates the complexity of managing multiple devices. By combining camera control, position processing, and tracking logic in the monitoring center, the system achieves high monitoring efficiency without proportionally increasing operational complexity.
3Ease of operation
If the monitoring system assumes the user does not move, then the system can simplify camera control, but the system fails when the user is moving
Solution Approach 1:
The system transitions from static camera control (assuming user immobility) to dynamic camera control that adapts to user movement. The monitoring center continuously receives position updates and adjusts camera positioning accordingly, enabling the system to maintain simplicity in control logic while adapting to moving targets through real-time position-based adjustments.
Solution Approach 2:
The system implements feedback loops where position information from the mobile terminal is continuously monitored and used to adjust camera control. This feedback mechanism allows the system to maintain simple operational principles while adapting to changing conditions, as the monitoring center automatically responds to position changes without requiring complex manual intervention.

AI summary
In a monitoring system, the management device estimates presence or absence of tracking by a security guard having the mobile terminal, extracts a moving object extracted from an image photographed by a camera as a tracking candidate when it is determined that the security guard performs tracking, and highlights the tracking candidate when displaying the tracking candidate photographed by the camera.
