次に、本開示の実施形態2について説明する。図3は、実施形態2にかかる車両制御システム900の全体構成を示すブロック図である。車両制御システム900は、生体認証を用いた車両に関する各種制御を実現するためのコンピュータシステムである。車両に関する各種制御とは、車両の開閉体の解錠又は施錠にかかる制御、並びにユーザの意思を必要とするその他の制御である。開閉体は、フロントドア、リアドア、ボンネット、給油口カバー、ドアガラス(窓)、及びトランクカバー等であってよい。ここで、車両の開閉体の解錠にかかる制御を第1制御と呼び、車両の開閉体の施錠にかかる制御を第3制御と呼び、ユーザの意思を必要とするその他の制御を、第2制御と呼ぶ。第2制御は、例えば、車両の開閉体の開放又は閉鎖にかかる制御であってもよいし、車両の電源を起動又は停止することであってよい。車両の電源は、イグニッション電源(IG電源)であってもよいし、アクセサリー電源(ACC電源)であってもよい。
図10は、実施形態2にかかる動作テーブルのデータ構造の一例を示す図である。動作テーブルは、登録動作の内容と、第2制御の内容とを対応付ける。
この場合、取得部102は、車両Vのドアが施錠状態であり、かつ所定の第1撮影画像取得条件を満たした場合、周辺カメラ120から取得した撮影画像を、第1撮影画像として、第1認証部103に供給してよい。第1撮影画像取得条件は、第1認証開始条件とも呼ばれてよい。第1撮影画像取得条件は、周辺カメラ120が撮影した撮影画像に含まれるユーザUが車両Vを基準とする予め定められる領域(第1撮影画像取得領域)に位置することであってよい。例えば、ユーザUが第1撮影画像取得領域に位置するか否かは、周辺カメラ120が撮影した撮影画像に含まれるユーザUの顔領域の大きさ又は幅若しくは長さが所定画素数以上であるか否かにより判定されてよい。また例えば、ユーザUが第1撮影画像取得領域に位置するか否かは、周辺カメラ120が撮影した撮影画像に含まれる、ユーザUの顔領域に含まれる所定の顔器官の特徴点を結ぶ長さが、所定画素数以上であるか否かにより判定されてもよい。顔器官の特徴点は、右目、左目、鼻の端点、口の端点、右眉の端点、及び左眉の端点うち少なくとも2つであってよい。一例として、顔器官の特徴点は、右目と左目である。また例えば、ユーザUが第1撮影画像取得領域に位置するか否かは、車両Vに搭載された複数の車載カメラの撮影画像を合成して得られた俯瞰画像から人物領域を検出し、人物領域の位置に基づいて判定されてもよい。また例えば、ユーザUが第1撮影画像取得領域に位置するか否かは、測距センサ等のセンサが第1撮影画像取得領域における人物の存在を検知したか否かにより判定されてもよい。このように第1撮影画像取得条件を満たすまでは第1認証部103による処理を開始しないことで、消費電力を低減することができる。
次に、本開示の実施形態3について説明する。実施形態3は、ユーザの位置により、動作判定対象となる登録動作の内容又は第2制御の内容が異なり得ることに特徴を有する。
第2駆動部140-1~140-6は、後述する第2車両制御部107aに接続されている。
次に、本開示の実施形態4について説明する。実施形態4は、情報処理装置が、生体認証を利用して、第2撮影画像に含まれる人物が登録ユーザであると判定した場合に動作判定を開始することに特徴を有する。尚、本実施形態4でも、生体認証は顔認証であるが、これに限らない。
次に、本開示の実施形態5について説明する。図23は、実施形態5にかかる車載システム1cの構成を示すブロック図である。車載システム1cは、実施形態4にかかる車載システム1bと基本的に同様の構成及び機能を有する。ただし車載システム1cは、ライト150と、スピーカ152と、情報処理装置100bに代えて情報処理装置100cとを備える。
次に、本開示の実施形態6について説明する。実施形態6は、実施形態5の変形例であり、情報処理装置が、動作判定処理において、登録ユーザ毎に学習した動作判定モデルを用いることに特徴を有する。
