1. A method for providing an analysis of a shot of a real or simulated projectile from a weapon on a target, comprising the following steps:
detecting a time of departure of a shot;
recording line-of-sight image data before the shot, immediately after the shot, and after the shot;
recording an image C at the time of departure of the shot;
generating a packet of data “A” with the line-of-sight image data immediately after the shot;
generating a packet of data “B” with the line-of-sight image data during a predefined time of ‘M’ seconds after the time of departure of the shot and line-of-sight image data recorded during a predefined time ‘N’ seconds before the time of departure of the shot;
analyzing the resolution of the shot by processing the packet of data “A” to determine if an object which is present on the image C is at a point of impact of the projectile, and in case the object is at a point of impact, identifying the object;
temporally analyzing the shot by a combined processing of the packet of data “A”, the packet of data “B”, and the results of the analysis of the resolution of the shot, the combined processing providing a deviation and an angular motion of the weapon;
marking shooting information on the line-of-sight image; and
generating quality metric data for the shot.
