Hi everyone, i'm realy excited about starting my first project in VHDl programming, by using FPGA card, my project is about monitoring cameras, and i didn't find any information about it, basiclly i'm realy confused about starting this project without any guides or information sources, it's my first step trought materials and FPGA card, except some basic tranings on it, i hope someone will help me to get what i need.

Thank you in advance.

That's not much info to go on to help you. You should probably start
with some simple projects to learn the nature of FPGAs and how to use
the tools, then work you way up to more complex projects until you
understand enough to tackle a project like image processing.

There are any number of starter pages on the web. A common project is a
traffic light controller.

What exactly do you want to do with the cameras?

first of all thank you for your reply,
My project is about surveillance camera, it means a camera that can stock a video, and only on a presence of mouvement, and after that we can display these sequence of videos on a LCD screen

Is the wind blowing enough to move lightweight objects enough that it should be displayed?

OK one step at a time.

What are the cameras you wish to use - are they analog or digital output?
If they are analog then what format of video do they provide?
If baseband then probably either RS170 or CCIR. You need to read up and
understand these video formats, then you will need to build an Analog to
digital converter to allow you to interface to the FPGA - how many bits? -
you need to understand sampling theory to get a handle on the conversion
rate you will need to preserve the analog bandwidth, and understand what
level of quantization you will need.

Having got the digitised input to the FPGA you will need to strip the sync
pulses from it to allow you to form the images properly into some kind of
frame store. You probably (almost certainly) will not have enough memory on
the FPGA for a frame store, so you will need external memory.

This will probably be DRAM or SDRAM. You need to define the devices your
need, speed and capacity, and understand how to drive the memory devices
from your FPGA.

If the cameras are digital - what format - camera link? Ethernet?
proprietary?

We have not even scratched the surface yet.

You need to do some background work and system design first before you even
think about coding the FPGA.

Just a few thoughts ...

As rickman suggested earlier - perhaps a traffic light controller.

You need to walk before you run - understand the fundamentals.

Personally I would suggest:-

1) Flashing LED - say 1Hz, 500ms on, 500ms off based on your system clock.

2) A counter that drives a decoder/seven segment display, using your 1Hz
output from 1)

3) A frequency counter - drives the seven segment decoder/display from 2)
and measures the frequency from 1)

When you have got that all going come back for some more help.

There are many USB webcams available. That should be easier than
interfacing to one with an analog output.

But it depends a lot on what you want it to do.

The first thing I would suggest is that you trim your posts when you
quote. There is no need to include the entire thread in every post and
it makes it hard for others to read. Just quote the parts you are
replying to.

I gave you a suggestion on how to get started. How well do you know an
HDL like VHDL or Verilog? Do you need to start with coding tutorials?
Or are you past that point yet?

Andy Bartlett suggested 3 excellent ones for you. Is there some
specific problem with his suggestions, or have you simply already
finished them?

After you get that done, if you're still interested in the motion
detection problem, then make a video generator that generates some simple
scene (horizontal or vertical bars are good, or a checkerboard) and shows
it on your LCD.

Once you've got that code nailed down, then work on interfacing memory to
your FPGA. This isn't trivial, so don't be surprised if it's hard.
Making sure you have the bandwidth to read in one frame buffer from a
camera while you read out another to a screen is harder. When you can
write a test pattern into RAM then read it back bit-correct, fast enough
to do video, then proceed.

Then, define some frame buffers in RAM, and make code that displays a
frame buffer from RAM on your LCD screen. In an ideal world this will
just be glue between the two things you've done already; in the real
world a beginner may find himself re-writing something.

Once that works, then tackle reading from the camera into a frame buffer
at the same time that you're reading out from a frame buffer to the LCD.
Success will be measured when you can wave your hand in front of the
camera and see it on the screen, perhaps delayed by a frame or two. At
this point, you'll be a lot less of a beginner than you are now.

Finally, you can then start trying to implement motion detection
algorithms. Have fun -- it ain't easy.

If you are more interested in the algorithm than the FPGA-ness of the
thing this may be far easier to do on a good fast PC, particularly if you
can find an image processing tool kit.

The FPGA work just to get video into and out of the FPGA is not trivial,
but it pales beside the work to do the motion detection -- and modern PCs
are set up to do that sort of image processing, in an environment that's
easier to code than inside an FPGA.
