To improve accuracy of matching candidate parts detected from an image in which a plurality of objects are captured.SOLUTION: An image recognition device 100 comprises: a generation unit for generating a plurality of pairs for first part candidates and second part candidates by combining the first part candidates 3-1 to 3-3 and the second part candidates 4-1 to 4-3; a first calculation unit for calculating a first estimated value indicating estimation that the first part candidate and the second part candidate are connected for each of the plurality of pairs; a correction unit for performing processing of correcting the first estimated value using the second estimated value as a weight for each of the plurality of pairs in a state where a part candidate 2-1 is connected to the first part candidate or the second part candidate, wherein the part candidate 2-1 is one of the part candidates that are already matched and are the second estimated value indicating the connecting estimation, and is different from both the first part candidate and the second part candidate; and a matching unit for matching the first part candidate and the second part candidate on the basis of the corrected first estimated value.SELECTED DRAWING: Figure 17 【課題】複数の物体が写された画像から検出された部位候補のマッチング精度を向上させる。【解決手段】画像認識装置１００は、第１部位候補３−１〜３−３と第２部位候補４−１〜４−３とを組み合わせて、第１部位候補と第２部位候補とのペアを複数生成する生成部と、複数のペアのそれぞれについて、第１部位候補と第２部位候補とが繋がっている推定を示す第１推定値を算出する第１算出部と、既にマッチングされており、繋がっている推定を示す第２推定値である部位候補どうしの一方であって、第１部位候補および第２部位候補のいずれとも異なる部位候補２−１が、第１部位候補または第２部位候補と繋がっている状態において、第２推定値を重み付けとして、第１推定値を修正する処理を、複数のペアのそれぞれについて実行する修正部と、修正した第１推定値を基にして、第１部位候補と第２部位候補とをマッチングするマッチング部と、を備える。【選択図】図１７
