OBJECT LOCATION ESTIMATION SYSTEM, OBJECT LOCATION ESTIMATION DEVICE, OBJECT LOCATION ESTIMATION METHOD, AND OBJECT LOCATION ESTIMATION PROGRAM

摘要

An object location estimation system is configured to comprise: a camera (101) and a tag reader (102) as an observation device which detects an object within an environment which is a subject for observation and obtains an observation value thereof; a location likelihood computation unit (104) which computes a location likelihood for an object of each observation value; an object location estimation unit (105) which estimates a location of an object; a correlation value computation unit (107) which computes a correlation value of an observation value and an object; an entry-exit candidate detection unit (92) which detects an object candidate for each observation device which either enters into an observation range or exits from an observation range; and an entry-exit object adjudication unit (110) which adjudicates an object which has either entered into an environment or exited from an environment.
