Rescue System Using Movable Bodies for Continuous Target Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rescue systems for individuals with dementia or similar conditions, such as those using stationary or moving cameras, often lose sight of the target as they move out of the camera's field of view, leading to ineffective monitoring and potential safety issues.
Innovation Solution
A rescue system comprising multiple movable bodies equipped with cameras and a server that communicates with them to identify and track the target, predicting the target's movement and switching camera monitoring to maintain continuous tracking, even when the target moves out of one camera's view, using inter-mobile communication and automated driving vehicles or drones for persistent surveillance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a stationary camera is used for monitoring, then the camera structure is simple and stable, but the search target who is moving will go out of the field of view
Solution Approach 1:
The patent transitions from stationary cameras to moving cameras mounted on vehicles. The moving cameras dynamically adjust their position and field of view to track the search target, ensuring continuous monitoring while covering a larger area. This resolves the contradiction by making the monitoring system dynamic rather than static.
Solution Approach 2:
The patent divides the monitoring task among multiple vehicles equipped with cameras. Each vehicle independently monitors a portion of the search area, and the server coordinates their efforts. This segmentation allows the system to cover a larger area while maintaining reliable continuous monitoring through coordinated multiple units.
2Area of stationary object
If a moving camera on a vehicle is used, then the field of view coverage is improved, but the search target who is stopping will also go out of the field of view
Solution Approach 1:
The server receives real-time position information from both the vehicles and the search target, continuously calculates the optimal monitoring vehicle, and provides feedback control by instructing vehicles to adjust their positions. This closed-loop feedback system ensures that the search target remains within the field of view regardless of whether the target is moving or stationary.
Solution Approach 2:
The system is designed to handle multiple scenarios (moving target, stationary target, target in different locations) using the same moving camera platform. By making the vehicle-mounted camera system universal, it can adapt to various target states and maintain reliable monitoring across different conditions.
3Area of stationary object
If multiple movable bodies are deployed to improve monitoring coverage, then the field of view coverage is improved, but the device complexity increases
Solution Approach 1:
The server acts as an intermediary that centralizes the coordination of multiple vehicles. It receives data from all vehicles and the search target, processes the information, and distributes control instructions to individual vehicles. This intermediary approach manages the complexity by providing a single point of control rather than requiring direct peer-to-peer coordination between vehicles.
Solution Approach 2:
Each vehicle is equipped with its own camera, position sensor, and control system, allowing it to independently perform monitoring functions and report to the server. This self-service capability reduces the overall system complexity by distributing basic functions to individual units rather than requiring centralized control of all components.

AI summary
A rescue system identifies and rescues a protection target, using information from a camera mounted on a movable body. The rescue system includes: a plurality of movable bodies; and a server configured to communicate with the plurality of movable bodies. The server is configured, when the protection target is identified, to (a) acquire positional information about each of the plurality of movable bodies and positional information about the protection target, and (b) select, as the protection target moves, a movable body which is to monitor the protection target, from the plurality of movable bodies.
