Abstract
A method of generating surface geometry information of an object within an imaged region using an imaging system comprising a camera and a source of structured light, the source of structured light comprising a source of a plurality of rays of light. The method comprising obtaining first image data comprising a plurality of pixels, the first image data comprising image data representing the object and first structured light incident on the object, the first structured light comprising a periodic pattern comprising a plurality of pattern elements and having a first spatial frequency projected from said source of structured light and obtaining second image data comprising a plurality of pixels, the second image data comprising image data representing the object and providing information associating each of the plurality of image pixels of the second image data with a ray of said source of structured light. The first image data is processed based upon the second image data to determine a relationship between each of the plurality of image pixels of the first image data and a pattern element of said pattern of the first structured light projected from said source of structured light and the surface geometry information of the object is generated based upon the determined relationship and position data indicating relative spatial positions of said camera and said source of structured light.
