Inclination angle detection device, the inclination angle detection method, and program

摘要

PROBLEM TO BE SOLVED: To provide a technology that reduces a delay for calculating a tilt angle.;SOLUTION: The tilt angle detection device includes: a first acquisition part 14 that acquires acceleration of a moving body; a second acquisition part 16 that acquires a movement distance of the moving body; an estimation part 22 that estimates a speed of the moving body on the basis of the movement distance and the acceleration; a speed difference calculation part 24 that derives a first speed difference by calculating a change in a speed; an acceleration integration part 20 that integrates the acceleration and thereby derives a second speed difference; and a tilt angle calculation part 26 that derives a tilt angle of the moving body on the basis of the first speed difference and the second speed difference.;COPYRIGHT: (C)2014,JPO&INPIT
