Abstract

A training system and method to calculate actual coordinates of a projectile impact at one or more screens has been disclosed. A projectile is launched at a screen. One or more targets are projected onto the screen. A calibrated sensor is directed at the screen surface. The sensor continually captures thermal images of the screen surface. The sensor comprises software to detect and isolate thermal images of the projectile impacting the screen. These impact images are transmitted to a computer connected to the sensor. The computer comprises software to calculate the actual impact coordinates relative to a projected target. The calculated coordinates are digitally sent to feedback devices for display purposes. The system further comprises virtual training scenarios that are triggered upon notification of actual impact coordinates. These training scenarios simulate real life situations.
