Notification Range Determination for Video Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video management systems face challenges in accurately tracking and notifying authorities about individuals of interest, as they may not effectively utilize the moving direction, capture position, and elapsed time of detected objects to determine appropriate notification ranges.
Innovation Solution
An information processing apparatus and method that determines a notification range based on the moving direction, capture position, and elapsed time of detected objects, and transmits relevant information to corresponding devices for effective tracking and notification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If notification is provided to all devices without range determination, then notification coverage is maximized, but information overload and irrelevant notifications increase
Solution Approach 1:
The patent applies local quality by determining a specific notification range based on the detected object's position, moving direction, and elapsed time. Instead of uniformly notifying all devices, the system calculates a localized geographic range where the object is most likely to be found and notifies only devices within this calculated range, thereby reducing information overload while maintaining notification accuracy.
2Reliability
If tracking range is expanded to cover all possible locations, then tracking coverage is maximized, but response time and system efficiency decrease
Solution Approach 1:
The patent implements dynamics by continuously updating the notification range based on the object's moving direction and elapsed time. The range is not fixed but dynamically calculated based on current motion data, allowing the system to focus computational resources on the most relevant areas and reduce response time by avoiding unnecessary searches in unrelated locations.
Solution Approach 2:
The system performs preliminary action by pre-calculating the notification range based on the object's detected position, moving direction, and elapsed time before actually transmitting notifications. This preliminary range determination allows the system to prepare and prioritize notification targets in advance, improving overall response efficiency.
3Measurement precision
If notification range is limited to immediate vicinity, then notification precision is improved, but legitimate tracking opportunities are missed
Solution Approach 1:
The patent applies dimensionality change by transitioning from a static, fixed-radius notification zone to a dynamic, direction-based notification range. Instead of using only distance from the detection point, the system incorporates the object's moving direction and elapsed time to calculate an elongated, directionally-oriented notification range, thereby maintaining precision while expanding appropriate tracking coverage.

AI summary
An information processing apparatus (10) includes: determination means (11) for determining a range for providing notification of information regarding a specific object on the basis of a moving direction of the specific object detected on the basis of an image, a position where the image has been captured, and an elapsed time since the image has been captured; and transmission means (12) for transmitting the information regarding the specific object to a device corresponding to the range determined by the determination means.
