TI DSP Developemt Baord for Stereo vision using two USB cameras

Is there any TI DSP Development board that can take image inputs (640 X 480 or 320 X 240) from two USB cameras simultaneously and process them in real time (i.e perform the stereo vision algorithms written in C) to generate a dense disparity map. It will be better if the DSP Development board comes with two USB ports and supports OpenCV.

P.S:- I will be using Logitech C270 webcams

Thanks in advance,

Pratesh

    Hi Pratesh Kumar,

    The most of the Omap and DaVinci processors have USB camera support but I can recommend you OMAP4 based Panda board because is has 2 USB ports. Also the linked below articles could be useful for Kernel USB camera support configuration and initial testing:

    Thanks Cvetolin ...
    Panda Board seems to be the solution.But I have following doubt:
    Does it have the capability of taking two USB video streams of 640 X 480 at around 20 fps simultaneously and then process them to calculate the depth. Because I am trying capture the same image via USB in my PC and it is working only upto 340*280 resolution videos and not for 640*480 video stream because of the USB limitations (as mentioned in : answers.opencv.org/.../videocapture-open-wont-open-second-camera)

    Pratesh,

    The panda board is equipped with OMAP44xx processor. The necessary for your project simultaneously USB video streams with resolution 640x480 @ 20 fps should not be a problem for OMAP4 processor as looking at the video performance specifications:

    • Delivers true 1080p multi-standard HD record and playback with the industry’s broadest support for multimedia codecs available today as well as programmability to add support for future codecs
    • Provides support for high definition stereoscopic 3D encode/decode (OMAP4430: 720p, OMAP4460: 1080p)

    which can be read at the product page at:

    I'm not familiar with the algorithm which you will use and the necessary performance for processing but this you can discuss in the OMAP4 dedicated E2E forum at:
