To appropriately calculate a distance in accordance with a state of an own vehicle or in the periphery of an own vehicle.SOLUTION: A camera 30 images a front side of a vehicle 2. A reference object identification section 22 identifies a reference object (e.g. a white line) from an image captured by the camera 30. A laser control section 23 sets a laser irradiation range in a range based on a position of a reference object. A LIDAR 40 radiates a laser beam to the irradiation range so as to receive reflection light of the laser beam. A first distance calculation section 24 calculates a first distance being a distance to an irradiation destination by the LIDAR 40 arranged in the vehicle 2 on the basis of a result of irradiation by the LIDAR 40.SELECTED DRAWING: Figure 3
【課題】自車両または自車両の周囲の状態に応じて適切に距離を算出する。【解決手段】カメラ30が、車両2前方を撮像し、基準オブジェクト特定部22は、カメラ30により撮像された画像から基準オブジェクト(例えば、白線)を特定する。レーザ制御部23は、基準オブジェクトの位置に基づいた範囲にレーザ照射範囲を設定し、LIDAR40が、当該照射範囲にレーザ光を照射し、当該レーザ光の反射光を受光する。第1距離算出部24は、LIDAR40により照射された結果に基づいて、車両2に設置されたLIDAR40による照射先までの距離である第1距離を算出する。【選択図】図3
