PROBLEM TO BE SOLVED: To detect mist on glass of a shooting range overlapping an angle of view of a camera of a vehicle-purpose imaging system, using the camera and laser sensor of the vehicle-purpose imaging system.SOLUTION: An imaging system 10 comprises: a camera 22 that shoots an outside of a vehicle across glass of the vehicle 1; a laser sensor 24 that outputs a laser toward the outside of the vehicle across the glass of the vehicle 1, and receives reflection light of the laser; and a mist detection unit that detects mist of the glass of a shooting range 52 overlapping an angle of view of the camera 22, using at least one of a shot image of the camera 22 and a light reception result of the laser sensor. The laser sensor 24 is configured to output the laser toward the glass of the shooting range 52, and receive the reflection light of the laser from the glass of the shooting range 52. The mist detection unit is configured to: (a) when the vehicle 1 is travelling, detect the mist of the glass using the shot image of the camera 22 and the light reception result of the laser sensor 24; (b) when the vehicle 1 halts, detect the mist of the glass using the light reception result of the laser sensor 24.SELECTED DRAWING: Figure 1
【課題】車両用撮像システムのカメラおよびレーザセンサを用いて、カメラの画角と重なる撮像範囲のガラスの曇りを検知する。【解決手段】撮像システム10は、車両1のガラス越しに車外を撮像するカメラ22と、車両1のガラス越しに車外に向けてレーザを出力し、レーザの反射光を受光するレーザセンサ24と、カメラ22の撮像画像およびレーザセンサの受光結果の少なくとも一方を用いて、カメラ22の画角と重なる撮像範囲52のガラスの曇りを検知する曇り検知部と、を備える。レーザセンサ24は、撮像範囲52のガラスに向けてレーザを出力し、撮像範囲52のガラスからのレーザの反射光を受光する。曇り検知部は、a)車両1が走行中の場合、カメラ22の撮像画像およびレーザセンサ24の受光結果を用いてガラスの曇りを検知し、b)車両1が停車中の場合、レーザセンサ24の受光結果を用いてガラスの曇りを検知する。【選択図】図1
