Study On The Tank Weapon Aiming Error Testing System

Tank gun aiming accuracy is one of the important indicators to measure the performance of the system.To satisfy the military products demands,a new type of calibration system has been designed,and the parallelism error expression of tank gun aiming accuracy can be expressed with tanks boresight axis and artillery in the tank in symmetry plane.By adding the distance through optical system to the laser collimation system in the sight front of sights,it can realize the laser beam collimation simulation,and at the same time it is convenient to the human eye observation.In order to calibrate the aiming accuracy of tank fire control system,one measurement system has been designed to measure the parallelism error between the sighting axis and the artillery axis.The laser beam is used to simulate the sighting axis and the artillery axis.The CCD camera and the MATLAB digital image processing technology are used to capture the image and extract the centroid of the spots.Based on the position coordinates of centroid,on the vertical direction and horizontal direction,the offset of the position of the two axes is calculated,and the collimation error of the tank fire control system has been finished.The results show that the measurement accuracy is 0.07 mil,which can meet the practical needs.
