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 (302) a 3DMM model. It further comprises matching (303) the 3DMM model to each of N images of the set in order to determine a set of parameters hi, ρi, λi, wherein hi describes the orientation of the matched model with respect to the i-th image; ρi describes the 3D shape of the model matched to the i-th image and λi describes the appearance/texture of the model matched to the i-th image. The method comprises calculating (304) relative positions of the cameras, from which the images were collected, based on 3D transformations Hij of the matched 3DMM model from the i-th image to the matched 3DMM model from the j-th image; and calculating (305) the total matching error Ec for the model as a sum of matching errors of a model described by parameters hc, ρc, λc to individual images:
