Abstract
The examples of the disclosure disclose measurement method and device of light source parameters, an illumination system and a terminal apparatus. The method includes: collecting signal values of a light source to be measured from a color sensor, the color sensor including at least six response channels; preprocessing the signal values that have been collected, the preprocessing including normalization processing and standardization processing; constructing model features according to the signal values that have been preprocessed, and determining a light source type of the light source to be measured according to the model features; inputting the model features and the light source type that has been determined into a color rendering index prediction model to obtain a color rendering index of the light source to be measured.
