PROBLEM TO BE SOLVED: To provide a virtual point determination device capable of reducing persons required for determination work of a virtual point for setting a virtual marker.SOLUTION: Such a pointer 1 which includes three markers M, M, Mand a tip part 20 for pointing a virtual point and can specify the position of the tip part 20 by a marker position on the pointer is used. Distances among the respective markers of the pointer 1 are known. The pointer 1 in which one marker Mamong the three markers is not recognized by cameras is photographed by a plurality of cameras. When a virtual point position is pointed by the tip part 20 of the pointer, the pointer 1 is detected by changing a state in which the one marker Mamong the three markers is not recognized by the cameras to a state in which the three markers are recognized by the cameras. The coordinates of the tip part 20 are acquired as virtual point coordinates from marker coordinates during pointer detection with the pointer detection as a determination input. |
