Non-uniform correction method of remote sensing image

The invention discloses a non-uniform correction method of a remote sensing image. The method comprises the following steps: obtaining a noise function coefficient of each picture element according to a deep sea imaging result and a radiation response model in a continuously variable integration time of a visible light near infrared array CMOS camera; obtaining a non-uniform correction coefficient of each picture element according to imaging results of the visible light near infrared array CMOS camera for a homogeneous source in different integration times and the noise function coefficient; determining the remote sensing image obtained by the visible light near infrared array CMOS camera; and performing denoising and non-uniform correction on the remote sensing image obtained by the visible light near infrared array CMOS camera according to the noise function coefficient and the non-uniform correction coefficient to obtain a remote sensing image of non-uniform correction of the visible light near infrared ar
