Is there a way to retrieve information from the camera on an android device?

Question

What I'm wondering is if I snap a picture of an analog gauge is there a way I can get the camera to pull information about the position of the needles on the gauge?

Take an analog alarm clock for instance. If I wanted to snap a picture of the clock and based on the position of the hour and minute hands receive a digital time where would I start?

If anyone has any information on this subject or can point me in a direction that would be excellent.

I hope i am wrong but I think there is no easy approach to that task. Based on my knowledge you have to implement some computer vision algorithm on your own to determine that. — Łukasz Kosiak, Sep 08 '14 at 12:30
Cool Idea, Get the image from cam and do some thing like edge detection with opencv — Thomas, Sep 08 '14 at 12:35
OpenCV seems the most promising. It's definitely a place to start anyway. — tommy-the-cat, Sep 08 '14 at 13:05

I Think the only way to do so is using OpenCV

Most of the code is in C++ or Python, but I found a sample in Java here.

Read about the OpenCV here.

Looks kinda complicated, wish you luck implementing it!
