Claim 33:
34. A system for localizing, in a space for comprising at least one determined object, an object element associated to a particular 2D representation element in a determined 2D image of the space, the system comprising:
a deriving block for deriving a range or interval of candidate spatial positions for the imaged object element on the basis of predefined positional relationships, wherein the range or interval of candidate spatial positions for the imaged object element is developed in a depth direction with respect to the determined 2D representation element;
a restricting block for restricting the range or interval of candidate spatial positions to at least one restricted range or interval of admissible candidate spatial positions, wherein the restricting block is configured for:
limiting the range or interval of candidate spatial positions using at least one inclusive volume surrounding at least one determined object; and
defining at least one surface approximation, so as to limit the at least one range or interval of candidate spatial positions to at least one restricted range or interval of admissible candidate spatial positions;

a retrieving block for retrieving, among the admissible candidate spatial positions of the restricted range or interval, a most appropriate candidate spatial position on the basis of similarity metrics,
wherein the restricting block is configured for defining at least one surface-approximation-defined extremity of the at least one restricted range or interval of admissible candidate spatial positions, wherein the at least one surface-approximation-defined extremity is located at the intersection between the surface approximation and the range or interval of candidate spatial positions, wherein restricting comprises defining at least one inclusive-volume-defined extremity of the at least one restricted range or interval of admissible candidate spatial positions which is located at the intersection between the range or interval of candidate spatial position and the inclusive volume.
