Claim 4:
5. A loading machine control device comprising:
a measurement data acquisition processor unit that acquires measurement data of a measurement device mounted in a loading machine that has working equipment;
a target calculation processor unit that calculates, on the basis of the measurement data, a position of a loading target to which an excavation object excavated by a bucket of the working equipment is loaded;
a bucket calculation processor unit that calculates position data of the bucket;
an overlap determination processor unit that determines whether or not the loading target and the bucket overlap each other in the measurement data; and
a working equipment control processor unit that does not control the working equipment when it is determined that a portion of the loading target, the portion being larger than a predetermined proportion, overlaps the bucket, and that controls the working equipment on the basis of the measured position of the loading target when it is determined that only a portion of the loading target, the portion being smaller than the predetermined proportion, overlaps the bucket,
wherein the overlap determination processor unit determines whether or not there is overlap on the basis of relative positions of the measurement device, the upper end portion of the loading target, and the bucket,
wherein the bucket calculation processor unit calculates a position of a lower end portion of the bucket, and
the target calculation processor unit calculates the position of the upper end portion of the loading target when an angle specified on the basis of the measurement device, the upper end portion of the loading target, and the lower end portion of the bucket is equal to or larger than a predetermined angle.
