I want to make a shooting range. How to register hits?

Question

Electronics

I want to create a shooting range for shooting from pneumatic weapons and there is a desire to somehow register hits. Those. you need some kind of conditional "sensor" that can do this. Nothing comes to mind, but if the understanding that it should be something like a resistive screen (as on old smartphones), but many times stronger, because. must withstand a hit from some kind of MP-512 aka "Murka" (shot energy 7.5 J).
Any ideas?

Answer 1

webcam and OpenCV

Answer 2

Maybe here you will find something suitable www.findpatent.ru/catalog/6518

Answer 3

because The camera and opencv have already been offered.
I will offer a slightly simpler option: a set of microphones and an algorithm based on the time shifts between the incoming bullet click signals on the stand, calculates the location.
the analog part of the circuit will turn out to be a fairly simple amplifier and comparator.
a minimum of three microns is enough, but with an increase in the number you can increase the accuracy and plus it will be possible to filter out left sounds.
The task is not rare, so you can look for ready-made solutions.
Well, the simplest solution in the form of a classic matrix of buttons with diodes. Cover the buttons with metal pads.
Minus: bullets will get stuck between the sites
Yes, and the blow is very short, there may be problems with catching. Yes, and a bunch of mechanics will be hemorrhoids in maintenance.

Answer 4

Not an electronics engineer, but I think this:
in one row on thin plywood there are small targets - cans, for example. In each bank - on a magnet, under a bank and thin plywood - too. When hit, the magnets are magnetized from each other, and the one that falls on the 10x10cm button (in order to take into account the spread). With the button, I think everyone understood that.
The option is stupid, no doubt, but it can help to come up with a better one.
