Research on Detection Method of Gun Barrel Based onLaser Circumferential Scanning and Centering Correction

The state of the gun barrel bore directly affects the firing accuracy and safety of the gun. To solve theproblem of low detection accuracy caused by inaccurate centering and poor perpendicularity between the laser beam andthe barrel wall in the current laser circumferential scanning detection method, a centering correction algorithm for thegeneral caliber gun barrel bore detection based on laser circumferential scanning is proposed. The parallelism of the axis ofthe detection device and the axis of the calibration pipe is completed by the calibration pipe and the attitude sensor on thedevice. According to the centering correction algorithm, the correction device completes the coincidence of the rotationaxis of the laser displacement sensor and the axis of the correction pipeline and the accurate verticality of the laser beamand the pipe wall, and completes the accurate measurement of the depth characteristics of the inner bore of the barrel. Thecorrection algorithm and device have important theoretical significance and practical value for improving the accuracy andefficiency of gun barrel detection, and studying the residual life and health monitoring of gun barrel.
