Inverse perspective transform from zero-curvature curve points application to the localization of some generalized cylinders

The authors proposed the localization of some kinds of generalized cylinders from their brightness image by solving the inverse perspective transform of their contours. Geometrical properties of perspective projection of zero-curvature points of space or planar curves are used for that. The main geometrical properties are exploited in two experiments. These experiments involve straight homogeneous cylinder and objects of revolution with a scaling function having at least one zero-curvature point. Knowing the model of these objects, it is shown that their spatial attitude can be recovered from their perspective image
