IMAGE DETERMINATION APPARATUS, IMAGE DETERMINATION METHOD, AND IMAGE DETERMINATION PROGRAM

To improve accuracy of reinforcing bar specification determination.SOLUTION: An image determination apparatus (1) comprises: an image processing unit (131) for calculating a diameter of a reinforcing bar from a photographed image of the reinforcing bar; an acquisition unit (132) for acquiring manufacturer information indicating a manufacturer of the reinforcing bar; and a specification determination unit (133) for referring, for each manufacturer, to reinforcing bar specification information in which specification data indicating a reinforcing bar specification and reinforcing bar range data indicating a range of the diameter of the reinforcing bar of the specification are associated with each other and determining the reinforcing bar specification from the calculated diameter of the reinforcing bar and the acquired manufacturer information.SELECTED DRAWING: Figure 2 【課題】鉄筋規格判定の精度を向上する。【解決手段】画像判定装置（１）は、鉄筋の撮影画像から鉄筋の径を算出する画像処理部（１３１）と、鉄筋のメーカを示すメーカ情報を取得する取得部（１３２）と、メーカごとに、鉄筋の規格を示す規格データと規格の鉄筋径の範囲を示す鉄筋範囲データとを対応付けた鉄筋規格情報を参照し、算出した鉄筋の径と取得したメーカ情報とから鉄筋の規格を判定する規格判定部（１３３）とを備える。【選択図】図２
