摘要： Existing methods and systems for recording of complex spatial information, which can be used to record, for example, the structure and plant and machine of oil rigs, generally require storage of large amounts of data. There is a need for systems and methods which can combine photographic images with 3D spatial locations and which can be operated using readily available computing equipment such as laptops and tablets. There is provided a method for recording spatial information, which comprises forming a point cloud representing objects within a given volume of space, obtaining at least one image from at least one given location within the given volume, determining those points in the point cloud which are visible from the given location and discarding points in the point cloud which are not visible from the given location, using the remaining point cloud data to determine the distance from the given location to locations on the surface of objects represented in the image and determining three dimensional coordinates of said surface locations.
