Collaborative calibration: extending shape from motion calibration

In this paper we summarize recent research results from a new technique of sensor calibration called shape-from-motion calibration. We first present the basic technique, which is an eigenspace analysis, and show that it includes the rigor of least squares without the full burden of measuring all the applied inputs. Next we present new research that removes another constraint of the calibration technique and extends the robustness to cover systems with slight nonlinearities.
