FIELD: physics.
SUBSTANCE: worn-out part of contact aerial differs from reflecting section of rigid body in suspension with said rigid body. Extraction of aerial worn-out section by white colour and extraction of background by black colour allow defining aerial worn-out section. Aerial type is selected to convert white area with greater number of pixels compared with that corresponding to maximum width of aerial in image from linear transducer into black area. Said conversion is conducted using the data obtained from identification of aerial image binary code in suspension with rigid body.
EFFECT: multiple and contactless measurement.
