MEASURING THE ANGLE BETWEEN A FIRST MEMBER AND A SECOND MEMBER UNDER DYNAMIC CONDITIONS |
摘要 |
Method and system for measuring an angle between a first member and a second member under dynamic conditions is provided. A first and second acceleration sensor and an angle measuring device (goniometer) are connected to the first and second member. Under dynamic and static conditions, the angle (α) is measured by the goniometer. Under static conditions, the inclination angle of the first member is measured using the first acceleration sensor and the inclination angle of the second member using the second acceleration sensor and the angle (α′) between the first and second members is calculated. Then the deviation is calculated between the angle (α) and the angle (α′). An error correction factor is calculated from the deviation between both angles (α,α′). The error correction factor is applied to future and/or previous measurements of the angle (α) between the first and second member done by the goniometer
