Title:
SENSOR ERROR CORRECTION APPARATUS USING JOINT SENSOR AND CORRECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2019/112158
Kind Code:
A1
Abstract:
The present invention relates to a sensor error correction apparatus which uses a joint sensor, a correction method, and a training system which utilizes such an error correction device. More specifically, a sensor error correction apparatus is an inertial sensor error correction device, which comprises: a first inertial sensor unit which is disposed on one side of a first support unit and measures, in real time, a first measured value, namely the angle of the first support unit; a second inertial sensor unit which is disposed on a second support unit and one side end of which is connected to another side end of the first support unit via a joint unit, so as to measure, in real time, a second measured value, namely the angle of the second support unit; a joint sensor which is mounted on the joint unit and measures, in real time, a third measured value, namely the joint angle between the first support unit and the second support unit; and a correction unit which corrects at least one out of the first inertial sensor unit and the second inertial sensor unit based on the third measured value, measured at the joint sensor.
