Abstract: A system for generating approximately coordinated region maps (RM), the system comprising a processing resource configured to: provide a data repository comprising one or more RMs, each mapping a corresponding region, and each including information of a relative location of synchronization objects (SOs) located within the corresponding region with respect to a coordinate-system (CS) origin of a CS of the corresponding RM; obtain a given RM including information of relative locations of given SOs located within the given region with respect to a given CS origin of a given CS of the given RM; retrieve, from the data repository, reference RMs that meet a criteria; identify the reference RMs associated with at least one SO that match at least one of the given SO, giving rise to optimization RMs; and determine, utilizing an optimization scheme, an approximate transformation between the given CS and the CSs of the optimization RMs.

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
