PROBLEM TO BE SOLVED: To recognize elevator passengers with high accuracy by image data even if a passenger is deficient in the image data.SOLUTION: An elevator having an image recognition function includes: a distance image sensor imaging a target and measuring a value of a distance to the target; and an image recognition device that includes a distance-image acquisition unit acquiring a distance image having the distance value from the distance image sensor, and that recognizes each passenger on the basis of the distance image. The distance-image acquisition unit acquires a plurality of distance images in time series, and the image recognition device extracts passengers on the basis of the distance images, extracts a position of each passenger from the distance images different in acquisition time to track the position of each passenger, detects deficiency of a passenger that occurs when the passenger is shielded behind another passenger, and recognizes the passengers including deficiency.

    【課題】画像データにおいて乗客が欠損する場合であっても、高い精度でエレベータの乗客を画像認識する。【解決手段】対象物を撮像すると共に対象物までの距離値を計測する距離画像センサと、距離画像センサから前記距離値を有する距離画像を取得する距離画像取得部を有して距離画像に基づいて乗客を認識する画像認識装置とを有する画像認識機能を備えたエレベータにおいて、距離画像取得部は時系列で複数の距離画像を取得し、画像認識装置は、複数の距離画像に基づいて乗客を抽出すると共に、取得時刻が異なる複数の距離画像から乗客の位置を抽出して追跡し、別の乗客に遮蔽されることで発生する乗客の欠損を検出し、欠損を含めて乗客を認識する。【選択図】図2
