Methods and systems for determining a gunshot sequence or recoil dynamics of a gunshot for a firearm

摘要

An apparatus, device, or method may detect aim or pointing direction of a firearm, and may display aim directions of the firearm for gunshots fired at a target. Sequence of bullet strikes by multiple gunshots may be determined. A method may comprise detecting gunshots of the firearm discharging live ammunition, measuring aim directions of the firearm substantially at times of detecting the gunshots, recording the times of the gunshots and/or sequence order of the gunshots, and generating output for displaying an image that includes bullet strike icons that represent bullet strikes on the target. Locations of the bullet strike icons in the image may be based, at least in part, on the measured aim directions of the gunshots.

1. A method comprising:
using a detector or a sensor to detect a gunshot of a firearm; using a 3D sensor to sense an aim direction of the firearm substantially at the time of detecting the gunshot; using electronics or a processor to set a reference direction based, at least in part, on the aim direction; using the 3D sensor to sense subsequent aim directions of the firearm after the time of detecting the gunshot; and using the electronics or the processor to:
compare any of the subsequent aim directions to the reference direction;measure recoil of the firearm, wherein the measuring is based, at least in part, on the comparing; anddisplay and/or record the measured recoil of the firearm.
