Camera Angle Shift Detection via Inclination Sensor Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle monitoring devices require time-consuming manual adjustments to correct camera angles due to potential shifts during imaging, often necessitating multiple personnel and prolonged visual recognition between the camera and display units.
Innovation Solution
A camera device equipped with an inclination sensor, memory for initial installation values, and light-emitting elements that display different light patterns based on inclination differences, allowing for early detection and rapid adjustment of camera angle shifts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the monitoring camera is fixed at the side of the road to capture images, then the camera can stably monitor vehicles, but the camera angle may collapse or shift during operation requiring time-consuming manual adjustment
Solution Approach 1:
The inclination sensor continuously detects the camera housing inclination and feeds this information to the processor, which compares it with the initial value and controls the light emitting elements to provide real-time feedback about camera angle status to the operator
Solution Approach 2:
The patent replaces the need for mechanical protractors and manual visual inspection with an electronic inclination sensor that automatically detects and reports camera angle status through light emitting elements
2Adaptability or versatility
If the monitoring camera and display unit are separated, then the system can be installed more flexibly, but at least two persons are needed to perform adjustment work
Solution Approach 1:
The inclination sensor and light emitting elements are integrated into the camera housing itself, allowing the camera to self-report its angle status without requiring external display units or multiple operators
3Measurement precision
If the operator performs visual recognition between display unit and camera for adjustment, then accurate alignment can be achieved, but it takes much time to perform the work
Solution Approach 1:
The patent replaces manual visual recognition and protractor-based measurement with an electronic inclination sensor that automatically and continuously measures camera housing inclination, providing rapid and accurate angle detection
Solution Approach 2:
The inclination sensor repeatedly detects the camera housing inclination continuously, allowing the operator to monitor camera angle status in real-time without intermittent visual checks
