Two cameras video capture using DM6467

Unfortnately, I am not aware of any example code for this.

Juan,there are so many video input ports,but the DM6467 could not use two of them simultaneously to caputure  two cameras video?

Just to make sure we are on the same page, DM6467 has a 16-bit video input port which can be used as a single 16-bit video input port (BT.1120)  OR two 8-bit video input ports (BT.656) OR a single 8/10/12 bit raw video input port.  Therefore, the hardware certainly supports what two simultaneous 8-bit video inputs; but I am afraid I do not know of any software examples to excercise this hardware capability.

Hi,

I would like that we comunicate together about the DM6467 please.

Thierno,

If you would like to talk to one of our representatives regarding your design, please use these forums or www.ti.com/support to contact your local support team.  Unfortunately, in my current role I am responsible for customers in my own region; additionally, I also help with the forums in my spare time; I like helping with the forums because customers anywhere in the world can search and see the answers posted here so I get more bang for my time spent.  This is why I heavily promote and contribute to this medium, but please note that I do have other responsabilities.  Thank you for your understanding.

Hi,

I wonder if the DM6467 can be programmed in matlab. I have demos in matlab (detection, tracking, etc.) and I managed to experiment with a live video stream over IP. Is that when I send this code to the DSP, while returning flow in the DSP can be treated?

this code is write on windows platform while the DSP (ARM's) running Linux. Do you have examples of applications of this kind? can display the feed from my DSP on a web server?

thank you in advance

Thierno,

Mathworks does provide the capability to interface Matlab and simulink to some development boards. As far as I remember you could use DM6446 EVM, DM642 EVM, C6713/C6416 DSK.

Note that the PC to target board interfacing is done via a JTAG emulator. You are required to use Code Composer Studio (CCS) in order to connect a JTAG emulator to the target board.

I have seen a demo where you had a model done in Simulink (using some TI basic blocks like http://focus.ti.com/docs/toolsw/folders/print/sprc589.html) then the model is converted to C and compiled. Then the executable is loaded to the C64x CPU via JTAG. Note that only the C64x+ side is supported, not the ARM side.

You would need to contact Mathworks to get more information.Typically if the DM6467 is supported by Malab and what version of CCS and Matlab need to be used together.
Here is a liitle description provided by Mathworks:

Hi,

thank you for your responses.
I ordered a card EVMDM6467 to a test. This card also has an ARM, I ask myself the question: programs converted to C from simulink windows plateforme can they be sent to the ARM, which is a linux platform?
I suppose the ARM hosts and runs all the programs which come in DSP?
Another question concerns Virtual Library VLIB: I received all the files cons I have a question: to do a tracking people or other tracking, how to use VLIB in this case? IT IS not provided comprehensive programs, there are only blocks or functions, what functions of VLIB can be put together to make tracking people?

I changed the settings in "edit parameter" but it's always the same, the squares are not stable and we would say that the reflection in the mirror is also track? :)
I used the demo (tracking people of matlab) with IP camera but I have a problem with the square move, there are tons of squares that move in all directions unlike the video of the demo (vipmen) where Each person is single track by a square. Have you worked on that?

if my block tracking people works very well, I can then generate C code to send to the DSP. is that all code generated by Simulink blocks (tracking people) should be sent to the DSP without special modifications?

I will contact Mathwork on DM6467 with ARM.

Again thank you in advance for your help.

NB: excuse me for my english, i'm french :)

hello bob,

you could walk to your system: the capture of 2 video streams in real time with the DM6467?
If yes, have you managed to post your video streams on a web page (internet) from the IP address of the DSP? how to do this?
DM6467T the flow may have 8 cameras analog input with the decoder TVP..., how to encode / decode these streams and display them on a web browser?
Thank you for your help
best regards
