WebAug 1, 1991 · In addition to providing photometric functions for photoclinometry, the work presented here has several other practical applications: (1) The empirical functions are easier to use than Hapke's function for computing normal albedos and for "flattening" spacecraft images prior to mosaicking. (2) The limb darkening of a body may be … WebThe term "photoclinometry" denotes a technique used to extract slope information from an image bright ness distribution. The word is derived from the Greek noun "phos" (light) and the Latin verb "clinare" (to bend).

WebThree photoclinometry images Emission 0° (acceptable 0-20°, limit 0-60°) Incidence angles 45° (acceptable 30-50°, limit 0-60°) Variation in illumination geometry of 90° (acceptable 40-90°, limit 10-120°). This refers to having different positions of the Sun with respect to the observed target. WebIn brief, photoclinometry (or shape-from-shading) uses image pixel brightness, incidence and emission angles, and a photometric function to solve the inverse problem of what … Webphotoclinometry techniques (i.e., shape-from-shading).
