Abstract

An arrangement for estimating a position representing a reference level in an image plane in a sequence of images is provided. The arrangement comprises obtaining information indicating positions and sizes of two or more objects in the image plane in one or more images of the sequence of images, wherein said sizes of two or more objects in the image plane correspond to a real-world object having a first size, determining a mapping between a position of an object in the image plane and a size of the object in the image plane on basis of said positions and sizes of the objects in the image plane in said one or more images, and using the mapping to determine an estimate of a position representing the reference level in the image plane in said sequence of images as a position in the image plane where a size of an object maps to a reference size.
