PROBLEM TO BE SOLVED: To improve detection accuracy of a moving body reflected on a road reflecting mirror.SOLUTION: An object detection device comprises: a road reflecting mirror detection unit 11; a radar wave transmission/reception unit 2; and a moving body detection unit 12. The road reflecting mirror detection unit 11 is configured to detect at least one road reflecting mirror 3 of a plurality of road reflecting mirrors provided respectively at a prescribed locations. The radar wave transmission/reception unit 2 is configured to transmit a radio signal to the road reflecting mirror, and receive a reflection wave signal reflected by the road reflecting mirror. The moving body detection unit 12 is configured to detect existence of a moving body on the basis of (A) the transmitted radio signal and (B) the reflection wave signal reaching the object detection device and is received by the object detection device after reflected upon the road reflecting mirror when the transmitted radio signal reaches the moving body and is reflected upon the moving body after reflected upon the road reflecting mirror.SELECTED DRAWING: Figure 2
【課題】道路反射鏡に映った移動体の検出精度を向上する。【解決手段】物体検出装置は、道路反射鏡検出部11と、レーダ波送受信部2と、移動体検出部12とを備える。道路反射鏡検出部11は、それぞれ所定の位置に設けられた複数の道路反射鏡のうちの少なくとも1つの道路反射鏡3を検出する。レーダ波送受信部2は、無線信号を上記道路反射鏡に送信して、上記道路反射鏡で反射した反射波信号を受信する。移動体検出部12は、(A)上記送信した無線信号と、(B)上記送信した無線信号が上記道路反射鏡で反射された後、移動体に到達して上記移動体で反射されたときに、上記道路反射鏡で反射された後、当該物体検出装置に到達して受信された反射波信号とに基づいて、上記移動体の存在を検出する。【選択図】図2
