An example system includes a patterned light projector operable to direct first and second portions of patterned light toward first and second surfaces, respectively, in an environment. The first and second surfaces may be at first and second distances, respectively, from the structured light projector. A graduated optical filter may be situated along an optical path of the patterned light. The graduated optical filter includes first and second regions to attenuate an intensity of the first and second portions of the patterned light, respectively, by first and second amounts, respectively. The first amount is greater than the second amount. The system additionally includes an image sensor operable to generate image data based on at least the first and second portions of the patterned light and a processor configured to determine first and second values indicative of an estimate of the first and second distances, respectively, based on the image data.
