To provide an adverse environment determination device, and an adverse environment determination method which can identify a site to be adverse environment for a device which recognizes an object by using image data.SOLUTION: An environment determination device 20 determines surrounding environment as adverse environment for a front camera based on a fact that effective recognition distance of a lane compartment line is less than predetermined first distance. Then, a type of the adverse environment is determined on the basis of a recognition state of the lane compartment line and/or a landmark, and environment supplementary information such as air temperature. For example, when the lane compartment line located in predetermined second distance or more and less than the first distance can be recognized, on the other hand, the landmark cannot be recognized, it is determined that the afternoon sun affects. In addition, when both of the lane compartment line located in the second distance or more and less than the first distance and the landmark can be recognized, it is determined that the type of the adverse environment is fog.SELECTED DRAWING: Figure 3
【課題】画像データを用いた物体認識をする装置にとっての悪環境となっている地点を特定可能な悪環境判定装置、悪環境判定方法を提供する。【解決手段】環境判定器20は、車線区画線の実効認識距離が所定の第1距離未満であることに基づいて周辺環境を前方カメラにとっての悪環境と判定する。そして、車線区画線及び/又はランドマークに対する認識状況、及び、気温等の環境補足情報に基づいて、悪環境の種別を判定する。例えば、所定の第2距離以上第1距離未満に位置する車線区画線を認識できている一方、ランドマークが認識できていない場合は、西日を受けていると判定する。また、第2距離以上第1距離未満に位置する車線区画線およびランドマークの両方を認識できている場合には、悪環境種別は霧であると判定する。【選択図】図3
