PROBLEM TO BE SOLVED: To accurately grasp a finished shape resulting from dredge in a dredge ship which performs the dredge multiple times by rotating a boom each time the dredge ship stops.SOLUTION: A position measuring section 241 measures a position of a dredge ship. A depth measuring section 242 measures a depth at the position of the dredge ship. An attitude measuring section 243 measures an attitude of the dredge ship. An elevation angle measuring section 244 measures an elevation angle of a boom. A rotation angle measuring section 245 measures a rotation angle of the boom. A feed amount measuring section 246 measures a feed amount of a lifting wire. A tilt angle measuring section 247 measures a tilt angle of a glove bucket. A computation section 218 computes a position of a reference point which becomes a reference for a position of a blade tip of the glove bucket on the basis of the position, attitude and depth of the dredge ship, the elevation angle and rotation angle of the boom and the feed amount of the lifting wire. A calculation section 219 calculates a finished shape resulting from dredge of the glove bucket on the basis of the tilt angle, blade tip data 222 and the position of the reference point. |
