PROBLEM TO BE SOLVED: To provide an environment recognition system with improved accuracy in detecting dirt on an on-vehicle camera.SOLUTION: An environment recognition system includes a camera loaded on a vehicle and analyzes an image of the camera so as to recognize the circumferential state of the vehicle on the basis of the analysis result of the image of the camera. A dirt detection section allows at least a partial line of an object that does not change on an image even when the vehicle moves to be set as at least one reference line, calculates an observation line corresponding to the reference line on the basis of the image of the camera, calculates a displacement amount of the observation line from the reference line, and then detects whether dirt is attached to the camera on the basis of the displacement amount.

    【課題】車載カメラの汚れの検出の正確性を向上させた外界認識システムを提供することを目的とする。【解決手段】車両に搭載されたカメラを備え、カメラの画像を解析して、カメラの画像の解析結果に基づいて車両の周辺の状態を認識する外界認識システムであって、汚れ検出部は、車両が移動してもカメラの画像上で変化がない物の少なくとも一部の線を少なくとも一つの基準線として設定し、カメラの画像から基準線に対応する観測線を算出し、観測線の基準線からの変位量を算出し、変位量に基づいてカメラに汚れが付着しているか否かを検出することを特徴とする。【選択図】図1
