Zusammenfassung:To make it possible to take appropriate action according to reliability of tracking.SOLUTION: A tracking device 100: comprises: an image acquisition unit 103 that repeatedly acquires images; an object reference information acquisition unit 104 that acquires object reference information on a tracking object included in the images; a surroundings reference information acquisition unit 104a that acquires surroundings reference information on the surroundings of the tracking object; a first similarity calculation unit 104a that calculates, for the images acquired in time series by the image acquisition unit 103, first similarity between a target image set in the images and the object reference information and detects a tracking object candidate image on the basis of the first similarity; a second similarity calculation unit 104a that calculates second similarity from the tracking object candidate image and surroundings reference information; and a reliability determination unit that determines reliability of the tracking object candidate image detected by the first similarity calculation unit 104a on the basis of the second similarity.SELECTED DRAWING: Figure 1 【課題】追尾の信頼性に応じて適切に対処し得るようにすること。【解決手段】追尾装置100は、画像を繰り返し取得する画像取得部103と、画像に含まれる追尾対象に関する対象基準情報を取得する対象基準情報取得部104aと、追尾対象の周囲に関する周囲基準情報を取得する周囲基準情報取得部104aと、画像取得部103によって時系列に取得される画像に対して、画像内に設定したターゲット画像と対象基準情報との第1の類似度を算出し、第1の類似度に基づき追尾対象候補画像を検出する第1の類似度算出部104aと、追尾対象候補画像と周囲基準情報より第2の類似度を算出する第2の類似度算出部104aと、第2の類似度に基づき、第1の類似度算出部104aにより検出した追尾対象候補画像の信頼性を判定する信頼性判定部と、を備える。【選択図】図1
