| description | An alignment method is provided for a color scannerless range imaging system whereby the separate optical paths of colored texture and monochromatic range images may be precisely aligned. The range imaging system includes an illumination system for illuminating a scene with modulated infrared illumination, image forming optics for forming an image of the scene, optical means for forming first and second optical paths between the image forming optics and an image sensor, a transponder subject to modulation located in the first optical path for amplifying and converting infrared light to visible light to form a range image on the image sensor. The alignment method includes the steps of providing a target having alignment indicia that can be imaged in both infrared and visible regions of the spectrum, capturing an infrared image of the target using the first optical path, capturing a color image of the target using the second optical path, and adjusting at least one of the optical paths so that the captured images are coincident. |
