PROBLEM TO BE SOLVED: To correct a position of a spatio-temporal image detection line in response to changes in an imaging direction of a camera. SOLUTION: An obstacle detecting device comprises a camera 1, mounted on a vehicle, for imaging a predetermined area around the vehicle in a predetermined imaging direction, an obstacle detecting unit 2 for detecting obstacles around the vehicle based on a temporal change in image data on a preset detection line in the predetermined area. The obstacle detecting unit 2 comprises a detection line correcting device 22 for acquiring an imaging direction of the camera 1 when an obstacle is detected, calculating the amount of deviation in the imaging direction of the camera 1 based on the acquired imaging direction and a default imaging direction of the camera 1, and correcting the set position of the detection line based on the calculated amount of deviation in the imaging direction.
