Vehicle Imaging Control for Battery and Memory-Limited Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle imaging systems face high battery load and memory capacity issues during object detection, leading to potential loss of evidence videos and lack of owner notification, making them ineffective for security.
Innovation Solution
An imaging system with multiple cameras, processors, and memory units that detect objects and notify the owner via a user terminal, allowing controlled imaging and recording only upon user instruction, thereby conserving battery and memory.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If imaging and video recording are performed continuously upon object detection, then security monitoring capability is improved, but battery consumption increases and memory capacity is depleted
Solution Approach 1:
The system performs imaging only at periodic intervals (e.g., every 3 seconds) rather than continuously, and video recording is activated only upon object detection. This periodic imaging approach reduces battery consumption while maintaining security monitoring capability by capturing snapshots at regular intervals without continuous power demand.
Solution Approach 2:
The system performs preliminary imaging at regular intervals before object detection occurs. When an object is detected, the system activates video recording to capture the specific event. This preliminary periodic imaging ensures that the system is already in a monitoring state, reducing the need for continuous high-power operation while maintaining security readiness.
2Reliability
If video recording is continuously performed, then evidence collection capability is improved, but memory capacity is depleted
Solution Approach 1:
The system records video only during specific periods when objects are detected, rather than continuously. Normal operation uses periodic snapshot imaging that consumes minimal memory. When an object is detected, video recording is activated to capture evidence, then stopped after a predetermined period. This approach preserves memory capacity while maintaining evidence collection capability for actual security events.
3Device complexity
If object detection is performed without owner notification, then system simplicity is improved, but security effectiveness is reduced
Solution Approach 1:
The system provides feedback to the owner through notifications when objects are detected. The notification device communicates detection events to the owner, allowing them to take appropriate actions. This feedback mechanism enhances security effectiveness by keeping the owner informed of potential threats while maintaining relatively simple system architecture through existing communication interfaces.

AI summary
An imaging system include at least one camera, and first to third devices. The at least one camera outputs an image obtained by imaging at least a part of surroundings of a vehicle. The first to third devices include first to third memories storing therein first to third programs, and first to third processors, respectively. The first processor is configured to execute the first program to perform first processing including: detecting an object around the vehicle; and outputting a first instruction to make an instruction to perform second processing in response to detecting the object. The second processor is configured to execute the second program to perform third processing including the second processing. The third processor is configured to execute the third program to perform fourth processing including outputting an image received from the second device and output by the at least one camera.
