POSITIONING APPARATUS
First Claim
1. A positioning apparatus that is mounted to an own vehicle, and performs positioning of the own vehicle, the positioning apparatus comprising:
- a light reception pattern acquisition unit that acquires a light reception pattern, the light reception pattern indicating a pattern of a change in strength of reflected light in relation to a position of the own vehicle, the reflected light being obtained using a light wave for measurement that has been transmitted from the own vehicle;
a first own vehicle position estimation unit that estimates a position of the own vehicle by referencing a database in which a reference pattern is recorded in advance, and by comparing the light reception pattern and the reference pattern, the reference pattern indicating a pattern in which a strength of reflected light is associated with each position in which a vehicle travels.

Abstract
A positioning apparatus is mounted to an own vehicle, and performs positioning of the own vehicle. The positioning apparatus acquires a light reception pattern. The light reception pattern indicates a pattern of a change in strength of reflected light in relation to a position of the own vehicle. The reflected light is obtained using a light wave for measurement that has been transmitted from the own vehicle. The positioning apparatus estimates a position of the own vehicle by referencing a database in which a reference pattern is recorded in advance, and by comparing the light reception pattern and the reference pattern. The reference pattern indicates a pattern in which a strength of reflected light is associated with each position in which a vehicle travels.

13. A method for performing positioning of an own vehicle by a positioning apparatus that is mounted to the own vehicle, the method comprising:
-
acquiring, by the positioning apparatus, a light reception pattern, the light reception pattern indicating a pattern of a change in strength of reflected light in relation to a position of the own vehicle, the reflected light being obtained using a light wave for measurement that has been transmitted from the own vehicle; and estimating, by the positioning apparatus, a position of the own vehicle by referencing a database in which a reference pattern is recorded in advance and by comparing the light reception pattern and the reference pattern, the reference pattern indicating a pattern in which a strength of reflected light is associated with each position in which a vehicle travels.
