Zusammenfassung: | PROBLEM TO BE SOLVED: To enable appropriate handling according to tracking reliability.SOLUTION: A tracking device 100 includes: an image acquisition unit 103 for acquiring images in repetition; an object reference information acquisition unit 104a for acquiring object reference information related to a tracking object included in the images; a peripheral reference information acquisition unit 104a for acquiring peripheral reference information related to the periphery of the tracking object; a first similarity calculation unit 104a for calculating first similarity between a target image set in an image and the object reference information on the images acquired in time series by the image acquisition unit 103, to detect a tracking object candidate image on the basis of the first similarity; a second similarity calculation unit 104a for calculating second similarity with the tracking object candidate image from the peripheral reference information; and a reliability judgment unit for judging, based on the second similarity, the reliability of the tracking object candidate image detected by the first similarity calculation unit 104a.
【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 |
