DANGEROUS DRIVING DETERMINATION DEVICE AND DANGEROUS DRIVING DETERMINATION METHOD

To provide a dangerous driving determination technique capable of determining that when a self vehicle changes a lane, the other vehicle repeats the same lane change as the self vehicle as dangerous driving of the other vehicle.SOLUTION: A dangerous driving determination device comprises an acquisition unit, a first detection unit, a second detection unit, a third detection unit, and a determination unit. The acquisition unit acquires an image captured by a camera mounted on the self vehicle. The first detection unit detects a lane boundary line from the captured image. The second detection unit detects another vehicle from the captured image. The third detection unit detects a lane change of the self vehicle based on the detection result of the first detection unit, and detects a lane change of another vehicle in the same direction as the lane change of the self vehicle that occurs after a lane change time of the self vehicle, based on the detection result of the first detection unit and the detection result of the second detection unit. When the number of times that the third detection unit detects a lane change of another vehicle in the same direction as the lane change of the self vehicle reaches a predetermined value, the determination unit determines that another vehicle is driving dangerously.SELECTED DRAWING: Figure 1 【課題】自車両が車線変更をした場合に他車両が自車両と同様の車線変更を繰り返すことを他車両の危険運転と判定することができる危険運転判定技術を提供する。【解決手段】危険運転判定装置は、取得部と、第１検出部と、第２検出部と、第３検出部と、判定部と、を備える。取得部は、自車両に搭載されるカメラによって撮影された撮影画像を取得する。第１検出部は、撮影画像から車線境界線を検出する。第２検出部は、撮影画像から他車両を検出する。第３検出部は、自車両の車線変更を第１検出部の検出結果に基づき検出し、自車両の車線変更時刻より後に発生した、自車両の車線変更と同じ方向への他車両の車線変更を第１検出部の検出結果及び第２検出部の検出結果に基づき検出する。判定部は、自車両の車線変更と同じ方向への他車両の車線変更を第３検出部が検出した回数が所定値に達した場合に他車両が危険運転を行っていると判定する。【選択図】図１
