First Claim
Patent Images

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 each of a plurality of overlapping fields of view within 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 and camera module to adjust lighting and imaging parameters between individual image captures such that a time relationship of the lighting and imaging parameters to individual image captures in the sequence of images in each of the plurality of overlapping fields of view is predetermined, and a time relationship of the lighting and imaging parameters to image captures with different light classes in each of the plurality of overlapping fields of view is predetermined; and

    the image processing module concatenating the individual images to form a set of images that are related to each other.
