PROBLEM TO BE SOLVED: To provide a technology capable of realizing measurement and determination of a sole with high accuracy with a relatively inexpensive device configuration regarding sole measurement.SOLUTION: A sole measuring device includes a box-like measuring instrument 2 and a PC. The sole measuring device comprises a box-like measuring instrument 2 and a PC. The measuring instrument 2 has a foot mounting plate 4； a pair of cameras 8 in a symmetrical position in a foot width direction (X direction) on a lower surface of a housing； a first type lighting element (E2, E4) lower than the foot mounting plate 4 near a first side (surfaces P3 and P4) as the lighting element 9, for example； and a second type lighting element (E8, E10) near a side edge in the foot mounting direction, for example on the outer periphery of the foot mounting plate 4. The PC controls the first type lighting element to be a first lighting state and acquires a first image from the camera 8 at a first timing during the measurement, measures the dimensions of the sole of the subject, and store and output the result information.SELECTED DRAWING: Figure 5COPYRIGHT: (C)2019,JPO&INPIT【課題】足裏測定に関して、比較的安価、小型の装置構成で、足裏の測定や判断を高精度で効率的に実現できる技術を提供する。【解決手段】足裏測定装置は、箱状の測定器２とＰＣとを備える。測定器２は、足載置板４と、筐体下面において足幅方向（Ｘ方向）で左右対称位置の２つのカメラ８と、照明素子９として例えば第１側面（面Ｐ３，Ｐ４）に近接して足載置板４よりも下方の位置の第１種照明素子（Ｅ２，Ｅ４）と、足載置板４の外周の例えば足幅方向の側端に近接した位置の第２種照明素子（Ｅ８，Ｅ１０）とを有する。ＰＣは、測定の際、第１タイミングで、第１種照明素子を第１照明状態に制御してカメラ８からの第１画像を取得し、第２タイミングで、第２種照明素子を第２照明状態に制御してカメラ８からの第２画像を取得し、被測定者の足裏の寸法を測定し、結果情報を格納および出力する。【選択図】図５
