1. An attitude angle derivation device, comprising:
an electronic interface configured to acquire a rotation angle related to a first coordinate system, the rotation angle being obtained from an angle sensor located in an object;
a memory configured to store the rotation angle and an attitude angle, the attitude angle being related to a second coordinate system of the object; and
a processor configured to acquire the rotation angle and the attitude angle by sampling including an irregular sampling, update the attitude angle based on a temporal change of the rotation angle derived from the rotation angle, and output the updated attitude angle via the electronic interface.
