Stereophotoclinometry on the OSIRIS-REx Mission: Mathematics and Methods

Abstract Stereophotoclinometry (SPC) makes it possible to extract the shapes of surfaces by combining information from images, namely stereo parallax data and surface shading slopes, with knowledge location a spacecraft. This technique has been used extensively in past few decades describe planets small bodies, such as asteroids comets. It also carefully navigate spacecraft around very case OSIRIS-REx mission ∼500 m diameter asteroid (101955) Bennu. paper describes mathematical foundation SPC, examples mission.
