US12449235 - Method for assisting with firing on a moving target, and associated device and assembly

A method for assisting with firing at a moving target, includes the steps of: displaying in a targeting window, superimposed onto the direct view of a scene, a main indicator creating a firing axis of a firing system; measuring a distance between the main indicator and a target in the scene; determining the speed of movement of the target; determining a targeting position, in the targeting window, anticipating an angular movement of the target relative to the firing axis, as a function of the speed of movement of the target, the speed of a projectile and the measured distance; and displaying, in the targeting window, a secondary indicator at the determined targeting position.

The patent describes a method and device for assisting in firing at moving targets by displaying a main indicator for the firing axis and calculating a secondary targeting position based on the target’s speed and distance. This system aims to enhance accuracy by anticipating the target’s movement relative to the projectile’s trajectory.

Claim 1

A method of assisting firing at a moving target, comprising the steps of: a. displaying, in a targeting window, a main indicator, superimposed on a direct view of a scene, the main indicator indicating a firing axis of a firing system, b. measuring a distance between the main indicator and a target of the scene on which the main indicator is superimposed in the targeting window, following reception of a command to designate the target, c. determining a speed of movement of the target following recognition of the target on at least two successive images of the targeting window, d. determining a targeting position in the targeting window, anticipating an angular movement of the target relative to the firing axis, between the firing of a projectile by the firing system and an impact of the projectile, according to the speed of movement of the target, a speed of the projectile and the distance, and e. displaying, in the targeting window, a secondary indicator at the determined targeting position. a. displaying, in a targeting window, a main indicator, superimposed on a direct view of a scene, the main indicator indicating a firing axis of a firing system, b. measuring a distance between the main indicator and a target of the scene on which the main indicator is superimposed in the targeting window, following reception of a command to designate the target, c. determining a speed of movement of the target following recognition of the target on at least two successive images of the targeting window, d. determining a targeting position in the targeting window, anticipating an angular movement of the target relative to the firing axis, between the firing of a projectile by the firing system and an impact of the projectile, according to the speed of movement of the target, a speed of the projectile and the distance, and e. displaying, in the targeting window, a secondary indicator at the determined targeting position.
