Abstract: The present invention relates to techniques for determining rendering information for virtual content within an augmented reality. The technique may comprise capturing an image comprising a graphical tag by an image capturing unit, wherein the graphical tag comprises one or more geometric objects, and the graphical tag representing coded information. Size reference information may then be obtained from the captured image and a distortion of a captured view of one of the geometric objects may then be determined. Thereafter, based on the size reference information and the distortion of the captured view, a relative position of the graphical tag to the image capturing unit may be determined. Based on the determined relative position, positioning information and scaling information for rendering the virtual content within an augmented reality relative to the graphical tag may then be determined.
