Problems solved by technology

[0009] (1) Only the illuminance is used as the judgment standard, without considering other important factors that affect the lighting quality such as color temperature, color rendering, stroboscopic, etc.
[0010] (2) It is necessary to make measuring instruments, which not only increases the cost but also makes it inconvenient to measure at any time

Abstract

The invention discloses a method for evaluating illumination quality through a cellphone, and the method comprises the steps: installing illumination quality evaluation application software in the cellphone; storing the optimal illumination optical parameter database; firstly starting a cellphone camera through the application software in use to continuously shoot a standard white board in a detected environment, obtaining a plurality of digital pictures, and storing the digital pictures temporarily; secondly calculating the intensity of illumination, the spatial distribution uniformness of the intensity of illumination, the color temperature, the color rendering index and the stroboflash amplitude through the digital pictures; and finally comparing the above parameters with the data in the optimal illumination optical parameter database, so as to judge the illumination quality. The method just needs the cellphone and the white board for evaluating the illumination quality of various types of application environment conveniently, and the evaluation indexes are scientific and reasonable.

Description

technical field [0001] The invention belongs to the technical field of lighting quality evaluation, in particular to a method for using a mobile phone to evaluate lighting quality. technical background [0002] People's study, work, and life are inseparable from lighting. The quality of lighting is directly related to people's physical and mental health and learning and work efficiency. Improper lighting can lead to vision problems such as nearsightedness, astigmatism, and other diseases. For example, some people have done comparative experiments to show that light intensity has a significant impact on children's myopia. Too much light or too much light will damage vision. Too high light can easily lead to dizziness and astigmatism, and too low light can easily cause eye fatigue and myopia. Strobe will make the pupillary sphincter fatigue due to overuse, thereby causing damage to the refractive system of the eyeball, and also cause adverse consequences of retinal neurons du...
