OBJECT IDENTIFICATION DEVICE AND OBJECT IDENTIFICATION METHOD

PROBLEM TO BE SOLVED: To provide an object identification device and an object identification method that can stably identify an individual object even when a plurality of adjacent objects move at the same speed.SOLUTION: A device identifying an object on the basis of a plurality of detection points to be detected by a laser radar is configured to comprise; recognizing a set of detection points in which a mutual distance among the detection points is within a predetermined distances Th, Thand Thas one cluster candidate; calculating stability indicative of a degree at which a shape of the cluster candidate recognized upon changing the predetermined distance is not changed within an allowable change amount Thto be maintained and detecting a cluster candidate of a shape having stability of T, Tand Tmore than a predetermined value Th; and associating a detected cluster candidate with a cluster candidate detected at a previous time for each predetermined time; calculating shape coincidence of each associated cluster candidate on the basis of a movement amount of the detection point included in the associated cluster candidate; and, when the shape coincidence is more than a predetermined threshold value, identifying the cluster candidate as one object.
