| description | To accurately detect failures of an object detection device.SOLUTION: An object detection devices 10, 10a, 10b, or 10c for detecting an object comprises: a light receiving unit 20 that has a light receiving surface on which a plurality of light receiving elements 220 are planarly arranged that can receive incident light RL including reflected light of emitted irradiation light IL, and outputs a first light receiving signal corresponding to a light receiving state of light receiving elements in a first area U1, which is an area of use predetermined in available areas Ar1, Ar2 on the light receiving surface; an image acquisition unit 115 that acquires, using the first light receiving signal, an ambient light image Img1 indicating the light reception intensity of ambient light; and a failure detection unit 113 that detects, using the ambient light image, failures of the light receiving elements in the first area.SELECTED DRAWING: Figure 1
【課題】物体検出装置の故障を精度よく検出する。【解決手段】物体を検出する物体検出装置１０、１０ａ、１０ｂ、１０ｃは、射出された照射光ＩＬの反射光を含む入射光ＲＬを受光可能な複数の受光素子２２０が面状に配列された受光面を有し、受光面における使用可能領域Ａｒ１、Ａｒ２における予め定められた使用領域を第１領域Ｕ１として第１領域内の受光素子の受光状態に応じた第１受光信号を出力する受光部２０と、第１受光信号を用いて、環境光の受光強度を示す環境光画像Ｉｍｇ１を取得する画像取得部１１５と、環境光画像を用いて、第１領域内の受光素子の故障を検出する故障検出部１１３と、を備える。【選択図】図１ |
