Abstract
Imaging apparatus includes an illumination subassembly, which is configured to project onto an object a pattern of monochromatic optical radiation in a given wavelength band. An imaging subassembly includes an image sensor, which is configured both to capture a first, monochromatic image of the pattern on the object by receiving the monochromatic optical radiation reflected from the object and to capture a second, color image of the object by receiving polychromatic optical radiation, and to output first and second image signals responsively to the first and second images, respectively. A processor is configured to process the first and second signals so as to generate and output a depth map of the object in registration with the color image.
