The invention relates to a haze image quality evaluation method and system, a storage medium and electronic equipment. The method comprises the following steps: S1, acquiring a haze image, and acquiring a first transmissivity image corresponding to the haze image based on a dark channel prior method; S2, acquiring a non-sky area of the haze image; and S3, obtaining a first incident light attenuation rate corresponding to the non-sky area according to the first transmissivity graph and the non-sky area so as to obtain the image quality of the haze image according to the first incident light attenuation rate. By implementing the method, the interference of the sky area on haze image quality evaluation is reduced by eliminating the sky area, so that the image quality evaluation effect is optimized.
