Abstract

The invention discloses a single-view three-dimensional ultrasonic nondestructive detection system. The system is characterized in that a CCD high-speed camera is connected to a processing system workstation through a data cable, wherein the CCD high-speed camera is used for acquiring the position relation between an ultrasonic wheeled phased array reflecting target and a measured workpiece in real time, and transmitting the detection result to the workstation; a high-level eddy and ultrasonic phased array host system is in transmission connection with the ultrasonic wheeled phased array reflecting target so as to display the ultrasonic detection result in real time; the high-level eddy and ultrasonic phased array host system is in network connection with the processing system workstation so as to realize the function of transmitting data in real time; a signal-view measuring system is used for corresponding the detected position information of the detector on the workpiece to a design theoretic mathematical model of a workpiece structure; detecting image result with good effect is selected from the ultrasonic detecting result is reduced to a theoretic three-dimensional mathematical model of the workpiece in order to perform data combination after measurement is finished. Therefore, the three-dimensional vision visualization of the ultrasonic nondestructive detection data based on the workpiece mathematical model can be achieved.

Description

technical field [0001] The invention relates to a new three-dimensional ultrasonic nondestructive testing system for workpieces with complex curved surface structures, in particular to a monocular vision three-dimensional ultrasonic nondestructive testing system, which enables one-to-one correspondence between the nondestructive testing results and the theoretical digital models of the tested workpieces, and realizes the three-dimensional visualization of the nondestructive testing results , belonging to the field of non-destructive testing systems. Background technique [0002] With the continuous improvement of the level of industrial automation, the processing technology of mechanical structures is also constantly improving. Irregular free-form surface structures are widely used in various fields, and the corresponding non-destructive testing work has encountered new technical challenges.
