Sir, can you please elaborate. We just used a airsoft gun. For a real gun we need better equipments. I think I didnot understand your question.
Kid,
Always remember the cardinal principal of science-----keep it simple stupid-----the more curves and options you will add to make it look good---the more problems you will have in making it work.
The mechanism of an air soft is different to that of a rifle first of all---the recoil---load and reload and the firing of the bullet will have a terrible effect on the electronics and opticals.
Here in the U S-----in police or FBI snipers----sometimes depending on the situation, they work in teams when there is like hostage taking scenario and the shooter has to shoot through a glass window. They prepare snipers to shoot in tandem with a micro second delay in taking the shot from one shooter to the other------when the target is behind a window glass pane.
What the concern is that the bullet when it hits the glass may deviate from its target and thus miss it completely----so what transpires is the shooter one fires at the glass pane at the target---which shatters the glass---a millisecond behind him the second shooter takes out the target---the second bullet right behind the first one by a few feet going through the open space as the glass has been blown out.
So---you may have a recognition device working in tandem with a shooter with his own rifle and scope---both of them looking at the target through their own lenses or visuals----both trained and working as a team----one is the spotter---the other is a shooter----both working in sync---both talking to each other and communicating what they see.
Now what that does for you is to make your recognition device simple and gets you to focus more on the work and the job that you know best---which is computers---electronics and visual facial recognition devices---that is what your primary focus and goal ought to be-----. The saying goes---CONTROL THE CONTROLLABLE------when you get into ballistics----they will be out of your league----it will take away from your primary goal and as you want to prove yourself a little too much----and all of it might end up in failure----.
You should also have a set of communication devices hooked up to the observer---hooked up to the shooter and hooked up to the base commander----your video device---what would it look like---a small bazooka with a screen at the back or what----.
In my humble opinion and trust me---my opinions are hardly ever "humble" set up the system and base it on the american sniper team---a spotter a shooter concept----I believe that you will have a winner---. Good luck to you and to your design. Make us proud.
