To highly accurately detect a seated position of an occupant present in a cabin by using one imaging section without a distance measuring function.SOLUTION: One example of an indoor monitoring device in the embodiment includes: an image acquisition section for acquiring a captured image obtained by imaging inside of a cabin of a vehicle by using an imaging section; and a position detection section for determining whether a head part of an occupant is present in the captured image, detecting the size of the head part, the position of the head part and a key point position of a key point other than the head part of the occupant in the captured image when the head part is present in the captured image, and detecting a seated position of the occupant in the cabin on the basis of the size of the head part, the position of the head part and the key point position.SELECTED DRAWING: Figure 4

    【課題】距離計測機能を有しない1つの撮像部を用いて、車室内に存在する乗員の着座位置を高精度に検出可能とする。【解決手段】実施形態の室内監視装置は、一例として、撮像部によって車両の車室内を撮像して得られる撮像画像を取得する画像取得部と、撮像画像内に乗員の頭部が存在するか否かを判定し、撮像画像内に頭部が存在する場合、撮像画像における、頭部のサイズ、頭部の頭部位置、および乗員の頭部以外のキーポイントのキーポイント位置を検出し、頭部のサイズ、頭部位置、およびキーポイント位置に基づいて、車室内における乗員の着座位置を検出する位置検出部と、を備える。【選択図】図4
