Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If lighting devices are installed around the image acquisition device, then additional lighting sources are provided to improve imaging quality, but the light quality is poor and affects imaging effect

Engineering Contradiction:
Improvelighting intensityVSAvoidimaging quality
Core Design Contradiction:
Illumination intensityVSReliability

Solution Approach 1:

The patent applies local quality by adjusting the installation positions of lighting devices to achieve uniform light field energy distribution across different regions of the reference surface. The system calculates and determines optimal positions where lighting devices should be installed to ensure each region receives appropriate illumination, transforming the uniform lighting approach into a localized, region-specific lighting strategy that improves overall light quality and imaging效果

Inventive Principle:

AI summary

The present disclosure provides a method and a device for determining an installation position of a lighting device as well as a light supplement apparatus, which can be applied in an intelligent lighting field. The method includes: determining initial light field energy distribution information according to illumination attribute information of each lighting device in a plurality of lighting arrays and a positional relationship of the lighting device with respect to the reference surface; updating an initial installation position of each lighting device in a symmetrical lighting tuple based on a comparison result between abnormal light field energy distribution information in the initial light field energy distribution information and a light field energy threshold, so as to obtain a plurality of candidate lighting arrays; determining candidate light field energy distribution information according to illumination attribute information of each lighting device in the candidate lighting arrays and a positional relationship of the lighting device in the candidate lighting arrays with respect to the reference surface; determining a candidate installation position as a target installation position in the case where abnormal light field energy distribution information in the candidate light field energy distribution information satisfies a light field energy range.
