Light intensity detection method and device, parameter determination method and device, equipment and storage medium

The embodiment of the invention provides a light intensity detection method and device, a parameter determination method and device, equipment and a storage medium. The light intensity detection method comprises the following steps that: the gray scale of a color component of actually measured screen light leakage is determined; the gray scale is corrected by adopting a pre-stored exponential correction value for the color component, so that a corrected gray scale can be obtained, wherein the exponential correction value indicates an exponential mapping relationship between the gray scale of the color component of the actually measured screen light leakage and the light intensity of the color component; based on a pre-stored linear fitting parameter for the color component, linear calculation is performed on the corrected gray scale to obtain light intensity corresponding to the color component; and superposition processing is performed based on the light intensity corresponding to thecolor component to obtai
