Abstract

A theoretic framework for unambiguous determination of a surface, moving in the gravity of earth or another known acceleration field, is presented. Optic acceleration is defined and new motion constraint equations are derived. The scaling problem between surface depth and velocity is solved, also for non rigid surfaces. Determination of orientation and shape is discussed. All methods derived are local, linear and unambiguous.
