Abstract: This invention belongs to measurement methods that can be used in light industry, when measuring the shape and size of the human body parts. Disclosed is a method, over the course of which, based on a series of photographs an image of a flat object of known shape and size is identified on each photograph. The body part area is isolated from the background in the image, and the area of an arbitrary body that does not belong to the projection of the human body part is cut out. Also disclosed is a method for searching an image of a flat object of known shape and size, its projection, and the camera location and orientation, over the course of which the predicted image of the flat object is compared to the real on. Here, the particle dynamics technique is used for isolating a human body part from the image background.

Abstract: The invention relates to measurement technology and is intended for measuring the shape, the internal dimensions and the flexibility of shoes. The proposed measurement method consists in using probes with indicators, which create tension on the measured surface. A camera and a flat marking band are used for tracing the shape of the internal surface of a shoe. On the basis of the sum of the images, a three-dimensional model of the internal surface of the tested shoe is made, and the flexibility properties are determined by scanning the object with different forces. A device comprises a body, a camera mounted therein, two or more probes with indicators, and a flat marking band. The invention makes it possible to increase accuracy and to reduce the labor intensiveness and time of measurements.
