With the wide introduction of waterproof standards (IP68) to the mobile phones industry and increasing in the popularity of amateur underwater photography, the questions of correction of different types of geometric distortion are more relevant than ever. Despite extensive research being conducted in the areas of radial distortion correction, there are almost no open datasets allowing numerical quality assessment of such algorithms. The SWD (Salt Water Distortion) dataset is the new image dataset in order to underwater distortion estimation and correction. Images were collected in water of various salinity (<1%, 13%, 25%, 40%) via two smartfone cameras with different angle of view and focal lengths. New dataset includes 662 underwater photos of calibration chessboard, for each image all corners of the chessboard squares were manually marked (35748 corners in total). Dataset description and code is available on https://github.com/Visillect/SaltWaterDistortion. For a fast download please use zenodo-get.
