The invention belongs to the technical field of measurement and relates to a swing angle measurement method, device and system. The swing angle measurement method includes the following steps that: first swing data and second swing data are acquired, the first swing data are obtained based on the reference data of a reference coordinate system and first swing angle measurement data, and the second swing data are obtained based on the reference data and second swing angle measurement data, wherein the first swing angle measurement data and the second swing angle measurement data are measured at different positions of an object to be measured; third swing data corresponding to a swing angle are obtained based on the first swing data and the second swing data; and the swing angle is calculated according to the third swing data. According to the swing angle measurement method, device and system of the invention, swing angle measurement is simultaneously performed on the different positions of the object to be measured, so that the obtained first swing data and second swing data are subjected to data conversion through data updating, and therefore, swing error caused by the vibration of the object to be measured is counteracted, and measured data are more accurate.
Description
technical field [0001] The invention relates to the field of measurement technology, in particular to a method, device and system for measuring a swing angle. Background technique [0002] Usually in the inertial navigation measurement, for the measurement of the yaw and attitude angle, the data is collected by the gyroscope, and the data is supplemented by the acceleration of gravity to obtain the measurement data. However, this method only corrects the error during the movement process, and does not solve the error caused by the vibration of other parts caused by the movement of the moving object during the movement process. For high-precision inertial measurement, the vibration caused by the moving object itself causes the direction of the coordinate system to change, and the measurement error needs to be eliminated through calculation, otherwise it will cause inaccurate measurement data and affect engineering design. Contents of the invention [0003] In view of this,...
