PROBLEM TO BE SOLVED: To provide, as an example, an occupant detection device which can accurately discriminate the presence or absence of an occupant who is seated on a seat of a vehicle.SOLUTION: This occupant detection device comprises an input part, a determination part, a detection part and a threshold change part. The input part inputs an imaged image in a cabin of a vehicle which is imaged by an imaging device, and a load detected by a load sensor arranged at a seat which is installed in the cabin of the vehicle. When the load is not smaller than a prescribed threshold, the detection part determines that the occupant is seated on the seat. The detection part acquires a face determination degree indicating the certainty of a face of the occupant in the imaged image from the imaged image. The threshold change part changes a threshold according to the face determination degree.SELECTED DRAWING: Figure 6
【課題】一例として、車両のシートに着座した乗員の有無を高精度に判別することができる乗員検知装置を提供する。【解決手段】実施形態にかかる乗員検知装置は、入力部と、判定部と、検出部と、閾値変更部と、を備える。入力部は、撮像装置によって撮像された車両の室内の撮像画像と、車両の室内に設けられたシートに設けられた荷重センサで検出された荷重と、を入力する。判定部は、荷重が所定の閾値以上の場合に、乗員がシートに着座していると判定する。検出部は、撮像画像から、撮像画像における乗員の顔の確からしさを示す顔判定度を求める。閾値変更部は、顔判定度に応じて閾値を変更する。【選択図】図6
