Abstract
A system for determining an approximate transformation between a first coordinate system and a second coordinate system, the system comprising a processing resource configured to: obtain an image captured by an image acquisition device of a mobile device; identify one or more synchronization objects within the image; determine first spatial dispositions of the synchronization objects with respect to a first coordinate-system origin of the first coordinate-system, the first coordinate system being a coordinate system of the mobile device; obtain information of second spatial dispositions of the synchronization objects with respect to a second coordinate-system origin of the second coordinate system; and determine, by employing an optimization scheme, utilizing the first spatial dispositions and the second spatial dispositions, the approximate transformation between the first coordinate-system and the second coordinate-system, the approximate transformation being usable by the mobile device for placing virtual objects with respect to the second coordinate-system.
