US12372329 - Method for calculated aimpoint correction in a digital weapon sight

Systems, devices, and methods are disclosed to correct aimpoint of a system of a weapon and affixed digital weapon sight. The method employs the components of a digital weapon sight configured together for a process of sensing of a ballistic event, storing of digital imagery data before and after a shot or series of shots, and then the performing of an image registration algorithm, via a cross-correlation type function. The image registration determines the misalignment between the images as a Cartesian shift, and aimpoint of subsequent shooting is corrected through application of adjusted reticle symbology or adjusted image sensor windowing. Preprocessing methods for enhancing image registration algorithm accuracy are presented.

The patent describes a method for correcting the aimpoint of a digital weapon sight by utilizing pre- and post-shot imagery data to determine misalignment through an image registration algorithm. This process adjusts the reticle symbology or image sensor windowing to enhance accuracy for subsequent shots.

Claim 1

An aimpoint correction method, which is applied to a digital weapon sight the digital weapon sight comprising a housing, a lens, a digital image sensor, a digital processor, addressable digital memory, a ballistic event and orientation sensor, an imagery output mechanism, and a manner of affixing to a weapon, wherein the method is characterized by comprising the following steps: storing pre-shot imagery and orientation data in the digital memory; sensing the occurrence of at least one ballistic event; storing post-shot imagery and orientation data in the digital memory; computing the two-dimensional coordinates of the centroid of the post-shot image as found within the pre-shot image by performing a cross-correlation type image registration function; and shifting an overlayed reticle symbol, and/or shifting the image sensor active window, according to the two-dimensional coordinates to correct subsequent aiming. storing pre-shot imagery and orientation data in the digital memory; sensing the occurrence of at least one ballistic event; storing post-shot imagery and orientation data in the digital memory; computing the two-dimensional coordinates of the centroid of the post-shot image as found within the pre-shot image by performing a cross-correlation type image registration function; and shifting an overlayed reticle symbol, and/or shifting the image sensor active window, according to the two-dimensional coordinates to correct subsequent aiming.
