Embodiment 1
[0028] A monocular underwater vision enhancement method based on dark channel priority, the steps are as follows:
[0029] (1) Establish a degradation model for the fogging and color shift phenomena of underwater images, and obtain the depth of field information of underwater images by calculating the parallax of bright and dark channels;
[0030] (2) Estimate the background color of the water body through the depth information;
[0031] (3) Obtain the transmission map of the underwater environment according to the depth of field information, and adjust the transmittance in the transmission map in an adaptive manner;
[0032] (4) Restore the image, and use color correction to perform subsequent processing on the image to remove the remaining color cast and adjust the brightness.
[0033] The specific steps of the algorithm are as follows, and the overall flow chart is as follows: figure 1 shown.
[0034] 1. Establishment of degradation model and acquisition of depth of fie...
