Description
Technical Field
The invention relates to the technical field of deep learning and polarization imaging, in particular to a turbid underwater polarization image restoration method based on a generation countermeasure network.
Background
The underwater image is used as a main mode for researching an underwater world, and has an important role in research in various fields such as underwater energy exploration, underwater archaeology, underwater ecological environment monitoring protection, underwater military and the like. However, there are very many particles under water, and the imaging quality is seriously affected by the effect of the backward scattering light in the conventional underwater optical imaging, such as low contrast, low brightness, blurred object details, and the like. This makes image-based target detection and analysis difficult to use underwater. At present, underwater image restoration methods are mainly divided into two categories, including restoration methods based on physical models and image enhancement methods based on non-physical models. The restoration method based on the physical model needs to consider the degradation process of the image, perform mathematical modeling on the underwater imaging process, estimate model parameters to restore the image through inverse push, or utilize a deep learning technology to learn a mapping function to restore the image. The image enhancement method based on the non-physical model mainly comprises a histogram equalization method, a color correction method, a fusion-based method and the like. Both techniques improve the image to a certain extent and improve the image quality. In contrast, image enhancement generally enhances visual perception, and is biased towards subjective judgment of people, and lost detailed information cannot be repaired. The image restoration method is to perform image modeling according to the image degradation model and design a mapping function to restore the original image. The polarization imaging technology is an image restoration technology which is widely researched at present, but the imaging effect still has certain limitation, and further application is influenced.

Specifically, in the present embodiment, 20 sets of images are captured, each set being added with 20 kinds of milk with different concentrations, and used for simulating the underwater environment 6 under 20 kinds of different turbidities, each turbidity being obtained by capturing 4 polarized images (including three polarized images with polarization directions of 0 °, 45 °, and 90 ° and one circularly polarized image) of the target 7 according to the capturing mode in step 1. A total of 12800(20 × 20 × 4 × 8) input images are obtained.
