Abstract

The invention discloses an ultrasonic probe calibration device. The ultrasonic probe calibration device comprises a fixed platform, wherein the fixed platform is provided with a laser radar, an ultrasonic probe fixing bracket and data acquisition equipment; an ultrasonic probe is connected with the upper end of the ultrasonic probe fixing bracket; the laser radar and the ultrasonic probe are electrically connected with the data acquisition equipment. The ultrasonic probe calibration device disclosed by the invention has the beneficial effects that the laser radar is used as a measurement element so that the calibration work of the calibration device is reduced and an operation step for calibrating the ultrasonic probe is reduced; the ultrasonic probe calibration device only takes the laserradar as the position measurement element and the structure is simple and easy to implement; the ultrasonic probe calibration device has no special requirements on the calibrated ultrasonic probe andis applicable to calibration of various ultrasonic probes taking air as a medium.

Description

technical field [0001] The invention relates to the technical field of ultrasonic positioning, in particular to an ultrasonic probe calibration device and a method for calibrating the ultrasonic probe. Background technique [0002] Ultrasonic detection technology is widely used in manufacturing, vehicle safety and other fields, and its detection range and measurement error are important indicators to measure its practicability. Therefore, before using the ultrasonic probe, its detection range and measurement error must be calibrated. [0003] The calibration of the ultrasonic probe needs to measure the exact position of the object to be measured, and compare it with the distance measured by the ultrasonic probe to obtain the measurement error of the ultrasonic probe. This error data can be used to correct the data of the ultrasonic probe, and can also evaluate the ultrasonic probe. characteristics. [0004] The difficulty of ultrasonic probe calibration is to accurately me...
