Title:
移動体、センサーモジュール及びセンサーモジュールの較正方法
Document Type and Number:
Japanese Patent JP7255364
Kind Code:
B2
Abstract:
A movable structure includes: a moving part pivoting about a predetermined axis; a sensor module provided at the moving part or at a site interlocked with the moving part; and a control device controlling the moving part and the sensor module. The control device controls the moving part in such a way that the sensor module takes a first attitude, and gives a calibration instruction to the sensor module. The sensor module includes: an inertial sensor; a calibration unit calculating an attitude of the sensor module based on an output signal from the inertial sensor in response to the calibration instruction and generating correction information based on a difference between the calculated attitude and the first attitude; and a correction unit correcting the output signal from the inertial sensor, based on the correction information.
