Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a depth estimation device, a depth estimation method and a program or a dimension estimation device, a dimension estimation method and a program, which can accurately estimate the depth or the dimension of an object captured in an input image in a real space.SOLUTION: The depth estimation device estimates the depth of each pixel in an input image based on a depth estimation model which is previously learned for estimating the depth on the input image. The depth estimation device receives an input of a piece of dimension information on a part of the input image where the dimensions on a real space are known, and calculates a parameter of a depth correction model for correcting the estimated depth of each pixel in the input image by using the estimated depth of each pixel corresponding to the part of the dimension information and the dimension information.SELECTED DRAWING: Figure 1 【課題】入力画像に写る物体の実空間上での深度又は寸法を精度良く推定することができる、深度推定装置、深度推定方法及びプログラム、又は、寸法推定装置、寸法推定方法及びプログラムを提供する。【解決手段】入力画像について、予め学習された、深度を推定するための深度推定モデルに基づいて入力画像の各画素の深度を推定し、入力画像中の、実空間上の寸法が既知な部分の寸法情報の入力を受け付け、推定された、寸法情報の部分に対応する画素の各々の深度と、寸法情報とを用いて、推定された入力画像の各画素の深度を修正するための深度修正モデルのパラメータを算出する。【選択図】図１
