DEVICE FOR MEASURING GEOMETRIC PARAMETERS OF THREE-DIMENSIONAL IMAGE OF OBJECTS MADE OF SOUND-REFLECTING MATERIALS Russian patent published in 2021 - IPC G01H17/00 G01B17/06 G01N29/00 

FIELD: metrology.

SUBSTANCE: invention relates to metrology, in particular to devices for measuring the geometric parameters of a three-dimensional image of objects made of sound-reflecting materials. Proposed is a device for measuring the geometric parameters of a three-dimensional image of products or objects made of sound-reflecting materials, containing a reference ring covering the controlled product or object, measuring organs in the form of ultrasonic receiving and transmitting sensors located on the inner surface of the ring, and a reference system. The reference ring is made movable in the vertical direction along the entire height of the measured object, and the ultrasonic receiving and transmitting sensors are made focusing with a focal length determined by the location of the geometric center of the reference ring, and the sensors are connected to a reference and control device that implements a working algorithm that provides the formation of a three-dimensional image of the object, visualized by analyzing the characteristics of the ultrasonic field using a computer device.

EFFECT: expansion of the nomenclature of measured objects and their shape parameters.
