Location estimation of cylinders from a 2-D image

This paper describes an approach to estimate the location from a cylinder considering both diffuse and specular models of reflection. Given the proper orientation of the cylinder, the Marquardt-Levenberg method from computational mathematics is used to estimate the parameters in the models based on several intensity profiles perpendicular to the cylinders orientation. While the nonphysical axis of the cylinder is used to determine its position, radius lighting direction and other reflectance parameters are also estimated. Experimental results for both synthesised and real images show that the method is robust with respect to noise.
