A system and method for determining an approximate transformation between coordinate systems

A method for determining an approximate transformation between a first coordinate system and a second coordinate system, the method comprising:

• obtaining, by a processing resource, an image captured by an image acquisition device of a mobile device;
• identifying, by the processing resource and by analyzing the image, one or more synchronization objects within the image;
• determining, by the processing resource, 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;
• obtaining, by the processing resource, information of second spatial dispositions of the synchronization objects with respect to a second coordinate-system origin of the second coordinate system;
• and
• determining, by the processing resource and 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.

A non-transitory computer readable storage medium having computer readable program code embodied therewith, the computer readable program code, executable by at least one processor of a computer to perform a method for determining an approximate transformation between a first coordinate system and a second coordinate system, the method comprising:

• obtaining, by the processor, an image captured by an image acquisition device of a mobile device;
• identifying, by the processor and by analyzing the image, one or more synchronization objects within the image;
• determining, by the processor, 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;
• obtaining, by the processor e, information of second spatial dispositions of the synchronization objects with respect to a second coordinate-system origin of the second coordinate system;
• and
• determining, by the processor and 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.
