Provided are a method and system for processing image data, the method comprising: capturing raw image data of multiple images of one or more scenes under one or more lighting conditions; machine vision processing the raw image data to generate machine vision data; classifying the machine vision data according to a type of the machine vision data; and storing the classified machine vision data in a multi-tiered data structure according to the machine vision data type, configured to enable each of the tiers of data to be processed independently of each other.

Method and system for processing image data

Provided are a method and system for calibrating parameters of an imaging system comprising at least one imaging device and broad and structured light sources, the method comprising: the at least one imaging device sequentially capturing broad light source image data and structured light source image data of one or more scenes using the broad and structured light sources, respectively; generating a photogrammetric model of the broad light source image data and a photogrammetric model of the structured light source image data using respective coordinates of the broad and structured light source image data; determining corresponding features in the respective photogrammetric models; iteratively solving parameters of the imaging system to correct variations between corresponding features in the respective photogrammetric models, converge the models and obtain calibration parameters; and applying the calibration parameters to the imaging system to compensate for errors in the relative positions of the imaging device and structured light source.

Method and system for calibrating imaging system

Provided is a method for generating a 3D point cloud and colour visualisation of an underwater scene, the point cloud comprising a set of (x, y, z) coordinates relating to points in the scene, the method operating in a system comprising at least one camera module, at least one structured light source, and a processing module, each of the at least one camera module being directed at the scene and having substantially the same overlapped field of view.

3D point clouds

The present invention relates to a method of processing survey data of an underwater scene comprising acquiring an augmented image of each of a plurality of fields of view within the scene, wherein each augmented image comprises at least a scene image of the scene, a location tag associated with that scene image, and metadata associated with that scene image.

Processing survey data of an underwater scene

The present invention relates to an underwater method and system for gathering range and dimensional information of subsea objects, the system comprising a camera module suitable for capturing images of sub-sea scenes; and a reference projection light source that, in use, projects a structured light beam onto a target. The structured light beam is preferably generated by a laser and may comprise spots, lines, grids and the like.

Gathering range and dimensional information for underwater surveys

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.
