IMPROVEMENTS IN RELATION TO UNDERWATER IMAGING FOR UNDERWATER SURVEYS
First Claim
1. A method of capturing sequential underwater image data of a scene for use in an underwater survey, the method operating in an underwater imaging system comprising a light module, an image processing module, a camera module, and a sequential imaging module, the light module comprising a plurality of light classes each light class having one or more light sources, wherein the steps of the method comprise:
- the camera module capturing a sequence of images of the scene, where the scene is illuminated by one or more of the light classes of the light module;
the sequential imaging module controlling the operational parameters of the light module to adjust lighting parameters between individual image captures; and
the image processing module concatenating the individual images to form a set of images that are related to each other.

Abstract
The present invention relates to methods and systems for performing underwater surveys, in particular on sub-sea installations such as oil and gas pipelines, risers, well-heads and so on. Further the invention relates to providing an augmented underwater image of a scene for use in an under-water survey, using an underwater imaging system comprising a light module, image processing module and a camera module, the light module comprising a plurality of light classes each light class having one or more light sources. The invention uses sequential imaging to provide the augmented output image.
