[Abstract]:Gun shunting velocity is an important standard for evaluating the performance parameters of gun control system. Aiming at the problems of low accuracy and complicated operation of traditional artillery gun velocity, this paper studies the measurement method of gun gun velocity based on CCD imaging. The main contents of this paper are as follows: 1. This paper analyzes the influence of the operating speed and the experimental environment of the system on the measurement error of the system. On the basis of this, a method of gun velocity measurement based on CCD is put forward. The block diagram of the system and the measuring principle of shot speed are given. According to the imaging results of CCD camera, a method of cross target coordinate recognition based on template matching is presented, and the algorithm is simulated in Matlab. An improved Gao Si fitting algorithm is used to calculate the center position of laser spot in the image. The real shooting range image is used to verify the algorithm in the software. The feasibility of the algorithm is proved. 3. A hardware platform based on FPGA image acquisition is designed. The image interface adopts Camera Link interface. Through Verilog programming language, the CCD camera driver BDR / GPS time information acquisition, image time bar code superposition and Camera Link interface driver program are completed. At the same time, In the upper computer, VC software is used to realize image preprocessing, time information recognition and target recognition. Finally, the center position of laser spot and the final velocity of gun shunting are calculated. Finally, the shooting range experiment of the system is carried out, and the experimental results are given to verify the feasibility of the system.
