Abstract: A method for capturing an image of a foot form a specific perspective using augmented reality (AR) includes generating an AR space based on a set of dimensions of a reference object, generating and displaying an AR foot placement object near the reference object, when a foot is on the AR foot placement object, generating and displaying an AR alignment object, a two-dimensional (2D) alignment object, an moving alignment object and a stationary alignment object; and when the 2D alignment object encloses the AR alignment object and the stationary alignment object encloses the moving alignment object, capturing an image related to the foot.

Abstract: A compression sock used in a foot measuring system, and worn on a user's foot that has a metatarsophalangeal joint area. The compression sock includes a sock cuff end, and a sock body. The sock cuff end is for insertion by the user's foot. The sock body is connected to the sock cuff end, and includes a high compression zone that surrounds the metatarsophalangeal joint area, and a standard compression zone that is proximate to the sock cuff end. A compression pressure value exerted by the high compression zone of the sock body on the metatarsophalangeal joint area is higher than a compression pressure value exerted by the standard compression zone on the rest of the user's foot.

Abstract: A foot scanning system is provided. The foot shape scanning system includes a reference device, at least one depth camera and a processing device. The reference device is disposed beside a measurement area. Each depth camera is configured to capture the measurement area to obtain an image. The processing device is coupled with the depth camera. The processing device determines a foot object in the image based on the reference device, and analyzes the foot object to calculate foot shape parameters of the foot object. Accordingly, a measurement device capable of conveniently and accurately measuring foot shape parameters is provided.
