Claims (1)
- 移動体の状態を光ビームで路面上に照射する路面描写装置であって、
将来の各時間における移動体の位置である将来位置を取得する将来位置取得手段と、
前記将来位置取得手段で取得した将来位置に応じて、光ビームの表示状態を設定する表示状態設定手段と、
前記表示状態設定手段で設定した表示状態に基づいて光ビームを路面上に照射する光ビーム照射手段と、
路面に照射された光ビームの線分長さを検出する画像処理手段と、
前記画像処理手段から送信される光ビームの線分長さに基づいて、自車両と他車両の衝突可能性を予測する予測手段と、
を備え、
前記表示状態設定手段は、前記光ビームの表示状態を線分状とし、前記移動体が前記将来位置に到達する目標到達時刻が遅いほど、前記光ビームの線分長さを長くし、
前記予測手段は、自車両と他車両の光ビームのうち、互いに交差または近接する光ビームの線分長さを抽出し、当該抽出された自車両と他車両の光ビームの線分長さの差が小さいほど、衝突可能性を高く算出することを特徴とする路面描写装置。
