<p>A method and apparatus for 3D scanning in which a transmission mask is projected on to the object scene and imaged by a camera, depth information being derived from the image by measurement of the illumination intensity from the camera image and computation from the measured intensity for the image, the mask having a first configuration having a transmission function f(x) varying regularly along its length and a second configuration having the same transmission function phase shifted by 180°, and means to project an image from each configuration on to the object scene.</p> |
