The Photogrammetry CubeSpaceport/RangeSituationalAwarenessWe can determine distances between objects and points of interest in 3-D space to auseful degree of accuracy from a set of camera images by using multiple camera views andreference targets in the camera’s field of view (FOV). The core of the software processingis based on the previously developed foreign-object debris vision trajectory software (seeKSC Research and Technology 2004 Annual Report, pp. 2–5).The current version of this photogrammetry software includes• the ability to calculate distances between any specified point pairs,• the ability to process any number of reference targets and any number of camera images,• user-friendly editing features, including zoom in/out, translate, and load/unload,• routines to help mark reference points with a “Find” function, while comparing them with thereference point database file, and• a comprehensive output report in HTML format.In this system, scene reference targets are replaced by a photogrammetry cube whose exterior surfacecontains multiple predetermined precision 2-D targets. Precise measurement of the cube’s 2-D targetsduring the fabrication phase eliminates the need for measuring 3-D coordinates of reference targetpositions in the camera’s FOV, using for example a survey theodolite or a Faroarm.Placing the 2-D targets on the cube’s surface required the development of precise machiningmethods. In response, 2-D targets were embedded into the surface of the cube and then paintedblack for high contrast. A 12-inch collapsible cube was developed for room-size scenes. A 3-inch,solid, stainless-steel photogrammetry cube was also fabricated for photogrammetry analysis of smallobjects.Contacts: Dr. Robert C. Youngquist , NASA-KSC, (321) 867-1829; andDr. John E.
