To provide a driving analyzer and a driving analyzing method that analyze various states of a driver such as a driver's intentional behavior from images of the driver.SOLUTION: A processing unit of a consciousness determination device generates a time series of detection elements which are regarded as a visual line direction indicating whether a visual line of a driver driving a vehicle is directed to any of a plurality of preset sight areas and an eye opening and closing state of the driver (S10-S40). Evaluation data is acquired with the use of a time window having a preset time width from the time series of the detection elements (S50). A plurality of feature amounts, including at least a result obtained by aggregation of appearance frequencies for each of the detection elements, are extracted from the evaluation data (S60). At least one of the tendency of the driver and the state of the driver is analyzed with the use of a function in which at least a portion of the extracted plurality of feature amounts is input (S70).SELECTED DRAWING: Figure 2
【課題】ドライバの画像から、意図的なドライバの行動を含む様々なドライバの状態を分析する運転分析装置及び運転分析方法を提供する。【解決手段】運転分析装置の処理部は、車両を運転するドライバの視線が、予め設定された複数の視領域のいずれに向いているかを示す視線方向、及びドライバの目の開閉状態を検出要素として、検出要素の時系列を生成する(S10〜S40)。検出要素の時系列から、予め設定された時間幅を有する時間窓を用いて評価用データを取得する(S50)。検出要素毎に出現頻度を集計した結果を少なくとも含む複数の特徴量を、評価用データから抽出する(S60)。抽出された複数の特徴量の少なくとも一部を入力とする関数を用いて、前記ドライバの傾向及び前記ドライバの状態のうち少なくとも一方を分析する(S70)。【選択図】図2
