Therefore, it is difficult for such methods to generalize to the comparison of haze image quality in different scenes
[0026] In summary, there is still a lot of room for improvement in the evaluation performance of the haze image quality of the existing schemes, and the evaluation method of the haze image quality and the range of image acquisition need to be improved

Embodiment Construction
[0073] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.
[0074] like figure 1 As shown, in the first embodiment of the haze image quality evaluation method of the present invention, the following steps are included:
[0075] S1. Obtain the haze image, and obtain the first transmittance map corresponding to the haze image based on the dark channel prior method; specifically, the atmospheric scattering model, which is widely used in the field of image processing under hazy weather, describes the atmospheric scattering process and the principle of ambient light attenuation. The detailed technical principle of the atmospheric scattering model under a single light source is as follows: Figure 5 As shown, the model divides the light reaching the imaging device into two parts: on...

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.
Description
technical field [0001] The present invention relates to the technical field of haze image quality evaluation, and more specifically, to a haze image quality evaluation method, system, storage medium and electronic equipment. Background technique [0002] Haze image quality assessment has broad application prospects. For example, estimating the concentration and impact of smog in time based on smog images can be used to predict air quality levels in meteorological forecasts, to estimate visibility in highway monitoring, and to calculate driving safety in the field of unmanned driving. [0003] Similar to image quality evaluation methods, haze image quality evaluation is also divided into two categories: subjective methods and objective methods. Among them, subjective image quality evaluation takes a long time and is difficult to apply in real-time in embedded devices, so it cannot be directly applied to the field of video surveillance. In the objective haze image quality ev...
