High Accuracy Electronic Target using triangulation

پست توسط NickFury »


I am looking at building an electronic target that uses the impact sound from the pellet hitting the paper. It will have multiple sensors (microphones) around the target (4 or more). The mic that hears the impact first needs to reset all timers, and/or start the sampling routine. As each mic hears the impact, it will need to time stamp each one, save to a variable, and then do a bunch of calculations to determine where the pellet hit the paper. I am quite well versed in PIC microcontrollers, but it appears that the RPi can do this much faster than a micro. With sound travelling at 1126 ft/sec, and an on-board processor speed of 1.2 GHz, what resolution could I expect in fractions of a millimeter? Ideally I would like sub 0.1 mm accuracy. What would be the best way to achieve this with the RPi, or is it possible?

Please help.

I didn't find the right solution from the Internet.
