Title:
SWING ANGLE CALIBRATION METHOD, ATTITUDE DETECTION METHOD, SWING ANGLE CALIBRATION SYSTEM, AND ATTITUDE DETECTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/090014
Kind Code:
A1
Abstract:
Step (S11) of this swing angle calibration method acquires position information of a predetermined position of a work machine (3) using a total station (TS) at a plurality of swing attitudes (K1 to K7) at which the work machine (3) makes only a swing in the left-right direction. Steps (S12, S13, S21 to S24, S31 to S33) calculate a swing angle (θi) at each of the swing attitudes on the basis of the position information. Steps (S34, S35) acquire a swing angle (θswi) at each of the swing attitudes (K1 to K7) on the basis of a detection value at the plurality of swing attitudes (K1 to K7) from a swing angle sensor (67). Step (S40) creates a swing angle error table (T) on the basis of a swing angle (θi) and a swing angle (θswi) at the plurality of swing attitudes (K1 to K7).
