Title SELF-POSITION ESTIMATION DEVICE, SELF-POSITION ESTIMATION METHOD, SELF-POSITION ESTIMATION PROGRAM, AND MOBILE OBJECT
Abstract

A coincidence degree calculation unit (12) calculates the degree of coincidence of both pieces of positional information when positional information acquired at a time (t) by a positional information acquisition unit (11) is subjected to parallel translation and rotational movement with respect to positional information acquired at a time (t-1). An estimation unit (13) estimates a self-position by changing the parallel translation amount (T) and rotational movement amount (R) of the positional information at the time (t) to search for the parallel translation amount (T) and rotational movement amount (R) at which the degree of coincidence becomes maximum. When some measurement point of the positional information at the time (t) is present within a distance (e) from some measurement point of the positional information at the time (t-1), the coincidence degree calculation unit (12) gives a predetermined point to the degree of coincidence.
