Method for assembling a projecting apparatus

Abstract

A method is provided for assembling a 3D sensing apparatus that comprises at least two projectors, wherein the assembling of the apparatus is carried out by ensuring that a pattern formed from a combination of images projected by each of the at least two projectors, is not formed along an epi-polar line or part thereof more than once. The method comprises the steps of: placing the at least two projectors at initial approximate physical positions within the 3D sensing apparatus; and, placing one or more projectors' protectors on top of the at least two projectors, thereby changing the projectors initial positions and automatically positioning them accurately in their pre-defined position and orientation by using the one or more projectors' protectors.
