To provide a raindrop detection device capable of efficiently determining a rainy weather.SOLUTION: A raindrop detection device includes: a camera 11 for imaging a windshield 2 to acquire information of the outside surface 2a of the windshield 2; and a control circuit 21 including a raindrop determination part 22 for estimating the existence of foreign matters on the windshield 2 from the information of the outside surface 2a of the windshield 2, and a storage part 23 storing data that states of the windshield 2 are a non-rainy weather state stored by machine learning. In the case that the raindrop determination part 22 determines that the existence of raindrops (foreign matters) on the windshield 2 is positive, the control circuit 21 determines whether to be a wet weather state by comparing the state of the windshield 2 with the data stored in the storage part 23.SELECTED DRAWING: Figure 1

    【課題】効率よく雨天と判定可能な雨滴検出装置を提供する。【解決手段】フロントガラス2を撮像して該フロントガラス2の外表面2aの情報を得るためのカメラ11と、フロントガラス2の外表面2aの情報からフロントガラス2上の異物の存在を推定する雨滴判定部22と、フロントガラス2の状態を機械学習により蓄積した非雨天状態であるというデータを記憶した記憶部23と、を備えた制御回路21を有する。制御回路21は、雨滴判定部22によりフロントガラス2における雨滴(異物)の存在が肯定された場合は、フロントガラス2の状態と記憶部23に記憶された前記データとを対比して雨天状態であるか否かを判定する。【選択図】図1
