To detect the three-dimensional position of an object with good accuracy when a rotationally moving door is opened or closed.SOLUTION: In a present object detector 400, a detection unit 405 acquires a time difference between a transmit timing at which a transmit wave is transmitted and a first receive timing at which a first receive wave is received and a second receive timing at which a second receive wave is received for the case where the rotational movement quantity of a rotationally moving door is a first quantity and for the case where the rotational movement quantity of the rotationally moving door is a second quantity differing from the first quantity; and detects the three-dimensional position of an object when the rotationally moving door is opened or closed on the basis of a first time difference which is acquired for the case where the rotational movement quantity is the first quantity, a second time difference which is acquired for the case where the rotational movement quantity is the second quantity, and a physical relationship between the transmit position and the first and second receive positions.SELECTED DRAWING: Figure 4
【課題】回動ドアの開閉時における物体の三次元な位置の検出を精度良く実行する。【解決手段】本物体検出装置４００において、検出部４０５は、送信波が送信される送信タイミングと第１の受信波が受信される第１の受信タイミングと第２の受信波が受信される第２の受信タイミングとの間の時間差を、回動ドアの回動量が第１の量である場合と第１の量とは異なる第２の量である場合とにおいて取得し、回動量が第１の量である場合に取得される時間差である第１の時間差と、回動量が第２の量である場合に取得される時間差である第２の時間差と、送信位置、第１の受信位置、および第２の受信位置の間の位置関係と、に基づいて、回動ドアの開閉時に物体の三次元的な位置を検出する。【選択図】図４
