Title:
MEASUREMENT DEVICE AND FLYING BODY
Document Type and Number:
Japanese Patent JP2018179579
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a measurement device and a flying body which measure even a low movement speed of the flying body with high accuracy.SOLUTION: A calculator 23 of a measurement device 20 calculates a movement speed of a drone 10 by integrating a measured value obtained from an acceleration sensor of an IMU 21 during movement of the drone 10 in the air. The calculator 23 stops the drone 10 in the air when an estimate of a measurement error of the acceleration sensor of the IMU 21 exceeds a threshold during the movement of the drone 10 in the air. The calculator 23 makes the drone 10 resume its movement after correcting the measurement error of the acceleration sensor of the IMU 21 on the basis of a measured value obtained from a rotating speed sensor 22.SELECTED DRAWING: Figure 1
