Android Target Practice App

Hi guys,

Basically I want to build an app that helps people to improve their fire-arm shooting skills.

I have a projector that is hooked up to an Android Device and projects onto a wall a target. The user has to shoot the target using a laser. The laser will shoot a beam of light for, let's say 0.5 seconds, on the wall where the user aimed. I have to capture that laser beam and determine where the user shoot the "bullet", if he hit the target etc...

My problem is that I don't know from where to start: - how can I detect that laser? - are there any libraries that might came in handy?

Any piece of information would be great!

Thanks a lot!

Look at the Color Blob detection example from OpenCV 2.4.2. It uses HSV color space. You can adapt it for your purposes.

If you can see the laser beam, a color detection technique might work.
