Abstract
The application provides a polarized image generation method and device, electronic equipment and readable storage medium, and relates to the technical field of image processing. The method comprises the following steps: obtaining a visible light image to be processed; inputting the visible light image to be processed into a pre-trained polarized image generator to obtain a target polarized image; the polarized image generator is trained based on a polarized image training set, a polarization loss function and an optical field vibration loss function; wherein the polarization loss function is used to measure the polarization loss of the predicted polarized image generated by the polarized image generator compared with the polarized sample image in the polarized image training set; the optical field vibration loss function is used to measure the optical field vibration loss of the predicted polarized image generated by the polarized image generator compared with the polarized sample image in the polarized image training set, thereby solving the technical problem that it is difficult to obtain a polarized image due to the harsh shooting conditions of a polarized camera in the prior art.
