Abstract

When imaging an above-water scene from underwater, the water volume in between forms a prism, introducing strong distortion to image even when the water surface is perfectly calm. The above-water scene from the underwater image is analyzed, and a coordinate transformation method based on pinhole camera model is formulated. Two widely used camera configurations are considered and the image rectification results with proposed method are presented.
