Abstract :
A method of determination of the relief of a planet surface region by a series of its images is described. It is based on the fact that at given directions of illumination and observation the brightness of a surface element depends on its orientation. Knowing this, one can determine the field of slopes from which it is possible then to reconstruct the relief.
