Abstract
A method for estimation of dimensions of an object present on images obtained from a set of N cameras and representing the same scene from different viewpoints, based on a 3D object model. The method comprises determining () a 3DMM model. It further comprises matching () the 3DMM model to each of N images of the set in order to determine a set of parameters h, ρ, λ, wherein hdescribes the orientation of the matched model with respect to the i-th image; ρdescribes the 3D shape of the model matched to the i-th image and λdescribes the appearance/texture of the model matched to the i-th image. The method comprises calculating () relative positions of the cameras, from which the images were collected, based on 3D transformations Hof the matched 3DMM model from the i-th image to the matched 3DMM model from the j-th image; and calculating () the total matching error Efor the model as a sum of matching errors of a model described by parameters h, ρ, λto individual images: The method further comprises estimating () the dimensions of the object based on locations of characteristic points from vector s, calculated as: whereinis the vector of the average 3DMM model shape, ρare elements of vector ρ, and ŝare eigenvalue vectors of the 3DMM model.
