Based on the laser triangulation method,a gun bore parameter detection device is designed.In order to improve the detection efficiency and detection accuracy of the system,the influence of the system sampling frequency and the motor speed is analyzed,and the installation method of the sensor and the mechanical structure of the system are also analyzed.The test results show that the system detection efficiency can be improved by decreasing the sampling frequency and increasing the speed.When the sampling frequency is 1 kHz and the speed is 3 r/min,the detection efficiency of the system is increased by 3 times;wavelet filtering on the data can remove burr,smooth curve and improve system detection accuracy.The errors of sensor installation and mechanical positioning are corrected by establishing mathematical models and correction algorithms.
