ISPRS 2003 Photoclinometry Made Simple...?
We describe a series of programs and scripts under development for the USGS digital cartography and image processing software system ISIS that will make it possible for users to create digital elevation models with single-pixel resolution from images of interest. The key program is an implementation of the two-dimensional photoclinometry (shape-from-shading) algorithm of Kirk (1987) with a graphical user interface designed to reduce the difficulty of operation substantially. Supporting programs and scripts can be used to estimate the surface and atmospheric photometric parameters used in the photoclinometric model, in order to maximize the quantitative accuracy of the results.
