# Identification of Riccati dynamics under perspective and orthographic observations

@article{Ghosh2000IdentificationOR, title={Identification of Riccati dynamics under perspective and orthographic observations}, author={Bijoy Kumar Ghosh and Hiroshi Inaba and Satoru Takahashi}, journal={IEEE Trans. Autom. Control.}, year={2000}, volume={45}, pages={1267-1278} }

The problem of identifying motion and shape parameters of a planar object undergoing a Riccati motion, from the associated optical flow generated on the image plane of a single CCD camera, is studied. The optical flow is generated by projecting feature points on the object onto the image plane via perspective and orthographic projections. An important result we show is that, under perspective projection, the parameters of a specific Riccati dynamics that extend the well-known "rigid motion" can…
