AI Technical Summary

Technical Problem

In existing lighting environment control technologies, the independent optimization of lighting strategies leads to insufficient visual continuity in transition areas, causing significant light abrupt changes, resulting in visual fatigue or discomfort. There is a lack of effective methods for judging visual discomfort and designing buffer zones.

Method used

By employing a multi-parameter feedback intelligent light environment collaborative control method, visual analysis is performed on adjacent areas to determine visual discomfort and calculate the amplitude of light change. Correlation analysis is used to determine the standard amplitude of light change, and buffer zone width and light gradation rules are established to solve the problem of visual discomfort caused by light change.

Benefits of technology

By effectively identifying areas of visual discomfort and establishing buffer zones, the problem of sudden changes in light caused by independent optimization of lighting strategies is solved, improving visual coherence and reducing visual fatigue and discomfort.

Abstract

This invention belongs to the field of light environment control technology. It provides an intelligent light environment collaborative control method and system based on multi-parameter feedback, comprising: calculating the visual index of each adjacent region; determining whether visual discomfort occurs in adjacent regions based on the visual index; identifying adjacent regions of visual discomfort; calculating the amplitude of light change abruptness based on the illumination parameters of each adjacent region; identifying adjacent regions of abruptness based on the amplitude of light change abruptness; determining whether visual discomfort is caused by light change abruptness through correlation analysis; obtaining the standard amplitude of light change abruptness based on the correlation analysis results; determining the width of the buffer zone and the light gradation rules of the buffer zone; and setting a buffer zone between adjacent regions of visual discomfort. This solves the problem of independent optimization of illumination strategies in adjacent regions while ignoring the visual continuity of transition areas, leading to obvious light changes when the human eye switches between different regions, causing visual fatigue or discomfort.
