Ultrasonic measuring method and device

Abstract

The present invention provides a method and a device for measurement of ultrasound waves. The method comprises the steps of: when a relative modeling object is located at a required relative distance,obtaining a plurality of measurement values corresponding to the relative distance and variance of the measurement values; determining an angle of divergence corresponding to the relative distance; establishing a measurement model configured to indicate a corresponding relation among the relative distance, the measurement values, the variance and the angle of divergence according to the measurement values corresponding to each relative distance, the variance of the measurement values and the angle of divergence corresponding to the relative distance; when a measured object is measured by manytimes by employing different relative distances to obtain the measurement values, inquiring the measurement mode to generate a probability distribution function for each measurement; and according tothe probability distribution function for each measurement, calculating and obtaining the shape of the measured object. Therefore, the method and the device for measurement of ultrasound waves extendthe measurement mode through measurement of the measured object by the ultrasound waves so as to solve the technical problem that a transparent measured object cannot be measured in the prior art.

Description

technical field [0001] The invention relates to the field of ultrasonic technology, in particular to an ultrasonic measurement method and device. Background technique [0002] As a way to obtain scene information in an unknown environment, obstacle measurement is widely used in robotics, medical care and other fields. [0003] In the related technology, the measurement of obstacles usually adopts the lidar measurement method. The radar with laser as the working beam is called lidar. It is composed of a laser transmitter, an optical receiver, a turntable and an information processing system. It becomes an optical pulse and sends it out, and the optical receiver restores the optical pulse reflected from the target into an electrical pulse, and sends it to the display, and then converts the electrical pulse corresponding to the received optical pulse and the electrical pulse corresponding to the emitted optical pulse Through comparison processing, it can accurately measure the...
