Abstract
In an abnormality detection device for detecting whether there is an abnormality in either of an optical sensor and a camera that are used to detect objects around a vehicle, a correlation value calculation unit calculates a correlation value between at least one of a reflection intensity image that is detected by the optical sensor emitting light toward surroundings of the vehicle and then receiving reflected light of emitted light and a background light image that is detected by the optical sensor receiving light from the surroundings of the vehicle while the optical sensor is emitting no light, and a captured image of the surroundings from the camera. An abnormality determination unit is configured to, in response to the correlation value calculated by the correlation value calculation unit being out of a predefined range, determine that there is an abnormality in either of the optical sensor and the camera.
