A method for carrying out comparison between the as-built state of an industrial plant and the associated CAD planning model, characterized in that the comparison is achieved by superimposition of unreliable components of the CAD model and digital images on the plant, whereby the superimposition is computed without any particular instrumentation within the plant, but only based on selected reliable components from the CAD model, whose physical installations are visible in the images. |
