PURPOSE:To prevent the overlapping detection and defective detection of reference coordinates by tracking a position to be inspected, detection thereof is completed, and displaying the position while overlapping a marker in a monitor. CONSTITUTION:A tracking means tracking and arithmetically operating the position to be inspected, which is indicated completely by a position setting means through a self-teaching system, and a marker generating means generating the markers indicating the completion of positional detection are added to a display device having the position setting means. When reflections to be inspected 21'(21'-1, 21'-2), 22'(22'-1-22'-4), the detection of positions thereof is completed, are moved from the position of a positioning mark 23, the position to be inspected is tracked and arithmetically operated by said tracking means. When the reflections 21', 22' to be inspected are located in a monitor picture 10, the markers 24 are overlapped to the reflections 21', 22' by said marker generating means, and the position is displayed. |
