Abstract
A method for mapping includes projecting onto an object a pattern of multiple spots having respective positions and shapes, such that the positions of the spots in the pattern are uncorrelated, while the shapes share a common characteristic. An image of the spots on the object is captured and processed so as to derive a three-dimensional (3D) map of the object.
