A method and apparatus for depth imaging by triangulation in which a pattern is projected on to an object scene and the scene, and the pattern, imaged, the projection and the imaging being spatially offset, in which the pattern has a characteristic dimension x and depth changes in the object scene cause deformations in the image of the pattern having a maximum dimension ?x, characterised in that ?x < x. |
