Abstract
A boom attitude detection device is equipped with: a GPS device that measures the position of the leading end of the boom; attitude detectors and that detect the attitude of the boom; and a calculation device. If the positioning reliability of the GPS device is high, the calculation device determines a correction value for correcting detection values of the attitude detectors to the attitude of the boom determined from the positioning value of the GPS device. If the positioning reliability of the GPS device is low, the calculation device corrects the detection values of the attitude detectors using correction values and determines the attitude of the boom.
