Abstract
A triangulation system comprising an area camera, a communication interface, a first image processing module, a second image processing module; wherein the area camera is arranged to obtain, at an acquisition rate, a stream of images of illuminated regions of an object; wherein the area camera is prevented from performing height calculations; wherein the communication interface is arranged to convey, in real time thereby in correspondence to the acquisition rate, the stream of images from the area camera to the first image processing module; wherein the first image processing module is arranged to process, in real time, the stream of images to provide first compressed information; wherein the second image processing module is arranged to process, at a non-real time image processing rate, the first compressed information to provide height information indicative of heights of at least the illuminated regions of the object.
