1. An information processing apparatus, comprising: a detection unit configured to detect a first imaging region of a first imaging device and to detect a second imaging region of a second imaging device, wherein the first imaging region is a three-dimensional first imaging space associated with the first imaging device and the second imaging region is a three-dimensional second imaging space associated with the second imaging device; a receiving unit configured to receive first information associated with the first imaging region and second information associated with the second imaging region; a determination unit configured to determine, based on at least the first and second imaging region information, whether a portion of the first imaging region is coincident within at least a portion of the second imaging region; and a classification unit configured to assign a classification to at least one of the first or second imaging devices, when the portions of the first and second imaging regions are coincident, wherein the detection unit, the receiving unit, the determination unit and the classification unit are each implemented via at least one processor.
