Vehicle Service Optical Layout for Distortion-Free Target Reading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle service systems face issues with large target support dimensions occupying space, ambient light reflections affecting readability, and optical distortions due to wide-angle lenses, leading to reduced accuracy and increased costs.
Innovation Solution
The system employs optical reader apparatuses with dual fields of view, positioning targets adjacent to the apparatuses to reduce target size and eliminate distortions, using infrared lighting to enhance readability and eliminate the need for wide-angle lenses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the target is placed at a significant distance from the vertical casing to be included in the field of view, then the target can be detected by the binocular stereoscopic vision system, but the lateral band occupation increases and calibration accuracy decreases
Solution Approach 1:
The patent transitions from a single wide-angle camera viewing both vehicle and target to a dual-camera system where one camera views the vehicle and another views the target. This dimensional separation in the imaging system allows the target to be positioned closer to the casing while maintaining detection capability, thereby reducing lateral space occupation while preserving calibration accuracy.
2Adaptability or versatility
If a wide-angle lens is used to detect both the wheel and the target at the same time, then the field of view is sufficient, but optical distortions increase and measurement precision decreases
Solution Approach 1:
The patent divides the imaging function into two separate cameras: one dedicated to capturing the vehicle/wheel and another dedicated to capturing the target. This segmentation eliminates the need for a wide-angle lens, thereby avoiding optical distortions while maintaining sufficient field of view coverage for each specific imaging task.
3Illumination intensity
If ambient light sources are present, then the service area is properly illuminated, but reflections occur and target readability decreases
Solution Approach 1:
The patent uses infrared illumination that is imperceptible to the human eye, converting the potential harm of ambient light reflections into a beneficial controlled lighting environment. The infrared source illuminates the target without creating visible reflections, thereby maintaining both service area illumination and target readability simultaneously.
