1. A method of determining spatial coordinates of a 3D reconstruction of at least part of a first real object comprising:
obtaining, from a first camera system, a first image comprising at least part of a first real object;
obtaining, from a second camera system, a second image comprising at least part of a second real object associated with known geometric properties, wherein the first camera system and the second camera system have a known spatial relationship;
determining a scale of at least part of the second real object based on the second image and the known geometric properties of the at least part of the second real object; and
determining, based on the known spatial relationship and the scale of the at least part of the second real object, one or more coordinates of a geometrical model of the first real object at absolute scale.
