The shooting is to shoot the set target according to a certain rule to test the shooting training effect and improve the shooting technology. Shooting training is an item of military training and is also a part of national defense education. Everyone is eager to master the series of consecutive shooting actions of lying down, loading, aligning the star for aiming at the target, pulling the trigger, etc. In shooting games and military shooting training, the statistics of shooting results are still mostly achieved through a manual target scoring method. Due to the influence of human factors, environmental factors and the like, the target scoring precision is not high, and athletes or soldiers cannot correctly know the scores of the athletes or the soldiers, so that the improvement of the target shooting level is not facilitated. Manual target scoring also presents significant problems in terms of efficiency and safety. Based on a processor and an electronic technology automatic target scoring system (electronic target), the system has absolute advantages and is widely applied compared with manual target scoring in the aspects of justice, real time, safety, simplicity, cost and precision.
