Hi all,

I need some help to start my project.

I want to create a simulink model using Xilinx Blockset, which will be able to track people with a camera.

For first, to help me start, can someone, please tell me how can I connect my From Video Device to the Gateway In Xilinx Blockset. I want first train on converting RGB to GrayScale. This is my first step to learn how to use Xilinx ISE.

Waiting for your answers

Thank's

You should have 3 "input" ports, each with 8bit, unsigned integer values.

Have a look at the" example located in

<ISE_Design_Suite_tree>/sysgen/examples/EDK/rgb2gray,

which is mentioned in the sysgen user manual.

As for the real hardware...this is quite a bit tougher, if there isn't anything pre-developed on your board!

Do you have an video-development kit or something?

Hi,

First thanks for answering me.

Yes, I have a Development Kit, which is the VSK Spartan 3A-DSP-3400.

Waiting for your answer.

Thanks

Well then you'll be able to get the real hardware to run as well!

Have a look at the example I told you and also the reference designs of your board...there you should find indications on how to access and use the 3 RGB  values of your camera

Hey,

Thank's for answering again.

I saw the example you told me and I don't really understand too.

So I think I'm gone go step by step.

For first, I think I'm just going to acquire the video from the camera through the board and directly put it on the DVI output.

Can you tell me how can I do this ? 

Do you have any instant dialog soft like skype or messenger to help me live ?

Thank you very much for your interest in my problem.

I'm just gone do a little presentation of myself by the way, I'm a french student in last year of licence, and i'm in internship in an S&D Lab in Québec, where I have to do a People Tracking Application on a xilinx FPGA .

Waiting for you.

I don't know your board, but I am sure there is enough stuff to read and also examples and reference designs.

Start with the very basic explanations of it.

You gotta do a little work by yourself, mate.

And another tip: Don't go for people tracking right away! Start with something very easy

• some simple image filtering
• or gradients  for example!

After you understand the basic concepts, start working on the real project..

[garnier47]

Yes, there are few examples pre-loaded on the board, but it's not very easy to understand.

That's why I want to go step by step.

What I want to know is, how can I manage the outputs ( RGB ) of my "From Video Device" to connect it with the Gateway IN ?

Thank's

If there is a full reference design (ISE or EDK project) have look there! The actual hardware conncection is in my experience with Reference Designs not made in System Generator.

Read the pdfs that came with your board, look for reference designs etc and try to get them running (which will be explained in the pdf)

If the full design is made with SysGen, then you will have to assign a "real" pin position to your "Gateway IN"-> double click on it and go to the tab "Implementation" . here you will have to specify the pin, which is conncected to your camera.

BUT: I reckon there is a decent reference design, where all this stuff (either fully in SysGen or in an ISE or EDK project) premade! Find this and understand it
