POSITIONING DEVICE, POSITIONING SYSTEM, POSITIONING METHOD, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To highly accurately perform positioning for decreased reliability of a sensor caused by an influence of ambient environment.

SOLUTION: A positioning device determines reliability of sensor values output from a plurality of sensors which detecting different objects respectively, using environment database. Further, the positioning is concurrently performed by a plurality of positioning methods using the sensor values added with the reliability to obtain a plurality of positioning results. The reliability of the positioning results is determined using the environment database. The positioning results added with the reliability are integrated to output a single piece of position information.
