A foot bottom surface measuring device includes a control mechanism, a measuring platform, which is arranged on one side of the bottom of the control mechanism, and the measuring platform is provided with several elastomers, and an image capturing mechanism, which is arranged on the end face of the control mechanism, can capture the image on the measuring platform.Thus, the tester can stand on the measuring platform and use the pressure difference of different height when stepping on the elastomer to calculate the shape of the foot surface. With the image capture mechanism, the image of the tester's foot (i.e. foot size) on the measuring platform and reflection unit can be captured, and the control mechanism can output the measurement according to the information of foot image, pressure difference, arch height, etc. It can achieve simple structure, easy operation and good measurement accuracy.一種足底曲面量測裝置，其包含有一操控機構；一量測平台，係設於該操控機構底部之一側，而該量測平台上係設有數個彈性體；以及一影像擷取機構，係設於操控機構之端面上，可擷取該量測平台上之影像。藉此，可讓量測者站立於量測平台上，利用腳踩在彈性體上會產生一個高度不同之壓力差，即可推算出足底曲面之形狀，配合影像擷取機構擷取量測平台與反射單元上之量測者足部影像(即足型尺寸)，讓操控機構依據足部影像、壓力差、足弓高度等資訊，輸出量測者足弓高度、足底曲面形狀與足部長、寬、高之立體影像，而達到結構簡單、易於操作使用以及量測精準度佳之功效。
