Adjustable Calibration Rod for Vehicle Night-Vision Camera Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing calibration methods for vehicle-mounted night-vision video recording apparatuses are complex, inconvenient, and limited to single vehicle types, relying heavily on software computing and requiring repeated calibrations due to factors like vibration and collision, which affect the accuracy and correctness of measurement data.
Innovation Solution
A calibration device with a holder assembly and adjustable calibration member, including a horizontally disposed calibration rod, allows for precise adjustment of the calibration member's height and angle, enabling easy calibration of different vehicle types by aligning the calibration rod with the vehicle-mounted night-vision video recording apparatus's display screen interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single vehicle type calibration tool is used, then the calibration process is simplified for that specific vehicle type, but the device cannot be used to calibrate other vehicle types
Solution Approach 1:
The calibration device is designed with a universal mounting structure that can adapt to different vehicle types through adjustable mounting positions and angles. The holder assembly includes movable components that allow the calibration rod to be positioned at various locations and orientations, enabling calibration across multiple vehicle types without requiring separate specialized tools for each vehicle model
2Measurement precision
If software computing is heavily depended upon for calibration, then calibration accuracy can be improved through calculations, but the calibration process becomes complex and requires multiple repeated operations
Solution Approach 1:
The invention replaces software-based computational calibration with a purely mechanical calibration system. The calibration rod provides direct physical reference lines that can be visually aligned with the night-vision display, eliminating the need for complex software calculations and multiple repeated calibration operations while maintaining calibration accuracy through precise mechanical positioning
