Abstract
A method for 3D imaging using phase shifted structured light, in which projection means project multiple phase shifted mask images of a transmission mask on to an object scene, the mask images being captured by a camera to form a camera image, depth information being derived from the camera image by measurement of the camera image and computation from the measurement for each of the phase shifted fringe patterns and a 3D scanner carrying out the method.
