Adaptive Vehicle Lamp Control for Camera Recognition Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The accuracy of vehicle recognition by vehicle control units is affected by varying illuminance conditions, leading to whiteout or blackout in images captured by vehicle cameras, which reduces recognition accuracy in certain regions.
Innovation Solution
A vehicle lamp system with an illuminance variable lamp and a lamp control unit that adjusts light intensity in specific regions to match the vehicle control unit's position information, increasing illuminance in low accuracy regions if it's too dark and decreasing it if it's too bright, to improve recognition accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the vehicle lamp emits strong light to improve visibility, then the illumination intensity increases, but whiteout occurs in the image causing recognition accuracy to decrease
Solution Approach 1:
The patent applies local quality by dividing the illumination into different regions (first region and second region) with different illuminance levels. The control unit sets the illuminance of the first region higher than that of the second region, allowing different parts of the scene to be illuminated according to their specific needs. This prevents whiteout in highly reflective areas while maintaining visibility in darker regions.
Solution Approach 2:
The patent implements dynamics by enabling the vehicle lamp to dynamically adjust its illumination pattern based on real-time conditions. The control unit modifies the illuminance distribution between different regions adaptively, allowing the system to respond to changing environmental conditions and maintain optimal recognition accuracy without causing whiteout.
2Measurement precision
If the vehicle lamp emits light to illuminate dark regions, then recognition accuracy in dark regions improves, but the overall light distribution becomes uneven causing blackout in other regions
Solution Approach 1:
The patent applies local quality by assigning different illuminance levels to different regions. The control unit specifically increases illuminance in the first region (where recognition accuracy needs improvement) while maintaining appropriate illuminance in the second region, avoiding uniform illumination that would cause blackout in non-critical areas.
3Device complexity
If the vehicle lamp uses fixed illuminance pattern, then the device complexity is low, but it cannot adapt to varying recognition accuracy requirements in different regions
Solution Approach 1:
The patent implements dynamics by enabling the vehicle lamp to dynamically adjust its illumination pattern based on real-time conditions. The control unit modifies the illuminance distribution between different regions adaptively, allowing the system to respond to changing environmental conditions and maintain optimal recognition accuracy without causing whiteout.
Solution Approach 2:
The patent applies universality by designing the vehicle lamp system to perform multiple functions: it can illuminate different regions with different intensities, adapt to various environmental conditions, and maintain recognition accuracy across diverse scenarios. The control unit enables the single lamp to serve multiple illumination needs simultaneously.

AI summary
A vehicle lamp system includes an illuminance variable lamp, a lamp-mounted camera, and a lamp control unit. After acquiring position information of a low accuracy region from a vehicle control unit, the lamp control unit acquires illuminance of the low accuracy region by referring to information acquired by the lamp-mounted camera, controls the illuminance variable lamp so as to increase the illuminance of the low accuracy region if the illuminance of the low accuracy region is less than a threshold, and/or controls the illuminance variable lamp so as to decrease the illuminance of the low accuracy region if the illuminance of the low accuracy region is equal to or greater than the threshold.
