Research On Laser Simulation Precision Shooting Ray Detection Location Based On Linear Image Sensor

The target shooting training for light weapons is the basis for individual training.If it cannot be guaranteed that the efficiency and quality of this training will directly affect the results of the training.However,in this regard,our country is still relatively backward,and still use the traditional method of real bullet training.This kind of shooting training has many problems such as large expenditures,high risks,and organization and implementation of tedious tasks.It is difficult to ensure effective and orderly training of troops.With the development of optoelectronic technology,microelectronic technology,network communication technology,multimedia technology and sensor technology,various new individual targeting training modes have emerged.This paper aims at the problem of real bullet shooting in training,and designs a laser simulation accuracy shooting and positioning system based on linear array CCD.The system replaced the bullet with a laser and replaced the traditional bullet paper target with a CCD cursor target.This not only improves the safety of training of troops and saves training costs,but also introduces the network communication technology,multimedia technology,etc.which making the target shooting training of light weapons more informative and intelligent,ensuring the efficiency and quality of the training effect of troops.The paper first introduces the overall framework of the laser emission position determination system,which includes the overall layout of the upper and lower position machines and the relationship between each module.The introduced the core principle of the paper,which includes the CCD sensor acquisition principle and the cursor target position determination principle.Then this paper begins to introduce the main part.The paper is divided into the upper computer and the lower computer.The upper computer realizes the control of the lower computer and the display of the data transmitted by the lower computer.The lower machine is divided into FPGA module and STM32 module.The STM32 module is the main controller module of the lower machine,and the FPGA module is the slave controller module of the lower machine.The task of the main controller module is to complete the data communication between the upper and lower units,receive the data transmitted from the controller and process it.The slave controller is used to drive the linear CCD sensor,drive the digital-to-analog conversion chip AD9822,drive the SRAM memory chip,and instantiate the FIFO IP core.The upper computer uses the C#language,developed on the.NET platform,and runs on the PC side of the command center.At the end of the thesis,the algorithm of laser shooting positioning system and the overall function test are introduced.The algorithm includes sliding average,median filter,double-edge center positioning method and so on.The overall functional test includes the upper computer control function test,data storage and display function test,and the lower computer CCD sensor analog signal image test.The test results show that the system is stable,reliable,and meets the design goals.
