The paper investigates the problems of creating a multimedia simulator with a laser emitter for training the correct use of various weapons in order to acquire the skills of targeted high-speed shooting. Specialized Software is designed to train novice shooters and improve the level of fire training in learning the techniques and rules of small arms shooting. The software component consists of separate software modules that allow the user to configure the interactive shooting range, create and run shooting exercises. Hitting the target is determined by the coincidence of the central pixel of the laser response (spot) on the projection image with one of the target pixels. Note that the laser emitter is attached to a real weapon and when you pull the trigger, a spot appears on the screen as a result of the shot. Along with the use of real weapons, computer graphics tools are used to create appropriate virtual environments and simulate a variety of situations in it, as close as possible to real conditions. Hardware and algorithmic shooting errors have been studied and methods for their reduction have been developed. Hardware depends on the parameters of the laser emitter, the size and characteristics of the projection screen, resolution and characteristics of the receiving camera-sensor. Algorithmic depends on the selected algorithm and frame processing methods. The hardware and algorithmic errors of shooting have been investigated and methods have been developed to reduce them. The analysis of the spots from the laser emitter on the projection image and the search for the centroid of the spot are carried out. An algorithm for determining the centroid of a spot through two-stage binarization of the image has been developed and tested, the thresholds of binarization that are optimal for solving the problem have been determined. The test results showed that the obtained accuracy is within the hardware component of the error, and the speed in decision-making is performed in real time.
