To provide a driving state monitoring support system for supporting the detection of driving a vehicle by a driver while doing something else using a fixed-point imaging device such as a drive recorder ordinarily installed in the vehicle with no need to install an acceleration device or a receiver in the vehicle.SOLUTION: The driving state monitoring support system of the present invention includes: a changed region extraction unit for comparing image data taken in time series by a fixed-point imaging device in which an imaging range is fixed, with its immediately preceding image data and its immediately following image data to generate a masking image indicating a changed region comprising changed pixels; a skin color region extraction unit for extracting a skin color region including skin color pixels from the changed region; a driver state determination unit for inputting the skin color region into an operation classification model that classifies a driver operation state into a plurality of classes, so as to classifying the driver operation state; and a vehicle traveling determination unit for classifying the masking image into a traveling classification model that classifies the vehicle into either a traveling class or a stopped class.SELECTED DRAWING: Figure 1
【課題】加速度装置や受信機などを車両に搭載する必要がなく、一般的に車両に搭載されているドライブレコーダのような定点撮像装置を用いて、運転者の運転中のながら運転を検出する支援を行なう運転状態監視支援システムを提供することを目的とする。【解決手段】本発明は、撮像範囲が固定された定点撮像装置により時系列に撮像された画像データを直前の画像データ及び直後の画像データと比較し、変化を有する画素の変化領域を示すマスキング画像を生成する変化領域抽出部と、変化領域から肌色の画素を含む肌色領域を抽出する肌色領域抽出部と、運転者の動作状態を複数のクラスに分類する動作分類モデルに対して肌色領域を入力し、運転者の状態のクラス分類を行なう運転者状態判定部と、車両が走行している走行クラス、及び停止している停止クラスの何れかに分類する走行分類モデルにマスキング画像をクラス分類する車両走行判定部とを備える。【選択図】図1
