To provide a technique capable of reducing a load according to a generation of learning data used for a device that detects a change in an image.SOLUTION: A learning data generation device 1 comprises: a detection part that detects a change region of a space between a first map and a second map on the basis of first map data indicating the first map and second map data indicating the second map indicating the same level with the first map of the space and indicating the space of the first map at a different time point; and a change region image acquisition part 24 that acquires an image corresponding to the change region detected by the detection part from a first image obtained by imaging the space expressed by the first map and a second mage obtained by imaging the space expressed by the second map.SELECTED DRAWING: Figure 1 【課題】画像内の変化を検出する装置が用いる学習データの作成に係る負荷を軽減することができる技術を提供する。【解決手段】学習データ生成装置１は、第１地図を示す第１地図データと、第１地図と略同一の空間を示し、かつ第１地図とは異なる時点の前記空間を表す第２地図を示す第２地図データとに基づいて、第１地図と第２地図との間における空間の変化領域を検出する検出部と、第１地図が表す前記空間が撮像された第１画像、及び第２地図が表す空間が撮像された第２画像から、検出部によって検出された変化領域に対応する画像を取得する変化領域画像取得部２４と、を備える。【選択図】図１
