ABSTRACT
Studying the relation between changes in image features derived by 3D transformations of a rigid object is a useful tool to deal with the 2D-3D pose estimation problem. Some applications in which the relative position and orientation of a moving object with respect to a fixed camera is necessary, may take advantage of this relation. Our purpose in this paper is to describe some properties of movement analysis over projected features of objects represented by lines. Then, having knowledge of the transformations applied to the object, we show that it is possible to estimate its orientation with only two different rotations, and also its position in the case length information is provided.
