Abstract
Apparatus and associated methods relate to ranging an object nearby an aircraft by triangulation of spatially-patterned light projected upon and reflected from the object. The spatially patterned light can have a wavelength corresponding to infrared light and/or to an atmospheric absorption band. In some embodiments, images of the object are captured both with and without illumination by the spatially-patterned light. A difference between these two images can be used to isolate the spatially-patterned light. The two images can also be used to identify pixel boundaries of the object and to calculate ranges of portions of the object corresponding to pixels imaging these portions. For pixels imaging reflections of the spatially-patterned light, triangulation can be used to calculate range. For pixels not imaging reflections of the spatially-patterned light, ranges can be calculated using one or more of the calculated ranges calculated using triangulation corresponding to nearby pixels.
