PROBLEM TO BE SOLVED: To extremely easily provide a drilling positioning control mechanism for an existing rock-drill loaded truck without the need for a large-scale alteration. SOLUTION: Movement target points P on a tip side of a guide shell and movement target points K on a rear side of the guide shell are marked on a monitor 2. The movement of the guide shell 12 is controlled in such a way that the tip side and rear side of the guide shell 12 may respectively correspond to the movement target points P and K. At this time, a light-emitting body 25 is attached to the tip side of the guide shell so that an object can be recognized on the monitor 2 to keep track of coordinates of the light-emitting body 25 on the monitor and to specify directional vectors in a camera coordinate system. A spatial line U passing through an installation point of the camera and oriented toward the tip side of the guide shell is assumed on the basis of the directional vectors in the camera coordinate system. A length L of a vertical line from the movement target point P on the tip side of the guide shell down to the spatial line U is displayed on a screen of the monitor. COPYRIGHT: (C)2011,JPO&INPIT |
