Abstract

Two new methods are proposed. The first is used to find attitude (or even position, if the planar shape size is available) of a planar shape in space from a single perspective view. The second is used to recognize a moving planar shape with two images. In the first method, a fast rotative transformation algorithm is designed for some geometric features of planar shape images, and a search tree algorithm is employed to find correct camera orientation based on a given shape model. Then the attitude of the planar shape with respect to the camera can be derived from calculated camera orientation. In the second method, the planar shape is identified among several models with two images by comparing results of the first method applied to each model.
