USB webcam support in C(running under LINUX)

Expand Post »
Ok, i am just starting out in C. This isn't my first programming language, though(i don't mean to brag, but i am a BASIC master), so i know quite a bit about computer architecture, and all that good stuff.

The project i am designing is a robot with stereo vision. I chose to learn C because, well, after looking at some of the code, i fell in love, and i chose Linux as my OS because of it's power.

I need to figure of how to get pictures from the two cams on my USB ports. I was told on another forum that there were libraries for USB Webcams, but i cant find any. Does anyone know where there is some? If so, please point me in that direction.

Sure, there is NOT A CHANCE that i will really understand the code, but it will get me started.:lol:


THANKS!!!

Use the "howto" keyword when searching for a lot of Linux information.

Re: USB webcam support in C(running under LINUX)

All of the links that i came up with showed how to gain webcam support in linux, not how to program it. Thanks for the contribution, though.

Hmpf, obviously not reading enough.

1st link.
"4. Framegrabbing Applications"
Follow some more links, download some source code, visit their homepages and start reading.

I think OpenCV is what your looking for, it's free, windows/linux and has a imagerecognition.

Re: USB webcam support in C(running under LINUX)

I am trying to do the same thing and it is difficult. the following may help.

1) I sugest you stay away from windows and use command line only.

2) Be aware that C is ment for all computers. Thus if you wnat to do somthing limitted to your machiene, like light up one pixel ( or display a whole screen) you will need a library to do that I suggest svaglib.

3) I am waiting on a book on webcams. It is from Intel & called
- USB Design by Example: A Practical Guide to Building I/O Devices
(2nd Edition... What you have picked is not a beginner project good luck
