Lighting environment measurement method based on image analysis

Abstract

The invention relates to the technical field of optical measurement and in particular relates to a lighting environment measurement method based on image analysis aiming at the influence of a lighting system on the environment. The method comprises the steps of imaging a standard reflecting plate, which is system-calibrated and coated with a standard color zone, by use of a color imaging device, and performing processing and analysis on the image information of the standard reflecting plate acquired by the imaging device by use of a computer connected with the color imaging device and a system analyzing and processing platform mounted in the computer, and consequently, obtaining the illuminance, the uniformity ofilluminance, the color temperature and the color rendering index of the environment of the standard reflecting plate. The lighting environment measurement method based on image analysis is capable of simplifying the field evaluation process during an environmental lighting test, and also capable of performing multi-point continuous testing on the lighting effect and performing long-time remote monitoring on the lighting effect.

Description

technical field [0001] The invention relates to the technical field of optical measurement, in particular to an image analysis-based lighting environment measurement method aiming at the impact of lighting systems on the environment. Background technique [0002] In the prior art, when testing environmental illuminance, illuminance uniformity, color temperature, and color rendering index, it is usually necessary to configure various special testing instruments such as illuminance meters, color temperature meters, and photometers to measure point by point at the set point. Some measurement methods require a lot of on-site testing equipment, continuous multi-point measurement takes a long time, real-time monitoring is difficult, too few test points are inaccurate when describing uniformity, too many test points are heavy workload, and it is impossible to remotely monitor for a long time. Defects in monitoring, especially the detection of road lighting, there is also a problem ...
