A vision method for computing 3-D location and shape parameters of a cone

A simple vision method to determine the 3-D location and shape parameters of a cone by using structured light is presented. The key concept in the proposed method is to convert the complex curved stripe pattern to an equivalent, but simpler, linear stripe pattern. The conic surface patch lying between the two visible silhouette edges is replaced by the plane defined by the two silhouette edges that cuts the cone. The appropriate geometric models are given to compute the cone axis and shape parameters representing the height of the cone and the radius of the cone base
