Developing Vision System using Davinci Video Processor

Other Parts Discussed in Thread: TMS320DM642

Hi All,

     This is my first post at DaVinci forum. I am a noob with DaVinci Video processors and have no experience with it. But, I am about to work with vision systems and I would like some initial guidance.

      Questions:

       1. If I was going to use an Aptina CMOS Image Sensor to develop into a vision system, what is the recommended method to do it? Would the DM816x EVM be a good development platform and be able to interface Aptina CMOS Image Sensor? Are there example programs that can be used as reference for development?

        I have seen this TI document below. There mention interfacing to TMS320DM642. Is there a Davinci Development kit that uses TMS320DM642.

    Markel,

    I can offer some thoughts and possible directions for you, but once you have more detailed questions, it may be good to start a new thread since I will not be able to go much further than this based on what I know.

    The DM816x is probably not the platform you want to use. The DM8168 does not have a sensor subsystem, so it would require a sensor that puts out video that has already been filtered and balanced, and so on.

    The DM814x and DM38x are the ones that are most often used for video applications and they have the ISP module to fork with the sensor directly. The DM385 is the most cost-effective solution, and the DM388 is the same with the addition of advanced noise filters.

    A good place to start could be the IPNC network camera reference design. You can find more information on it at IP Net Camera Solution or here.

    The better place to start would be to search for "aptina" on the TI Wiki Pages, then TI.com, then the E2E forum to get an idea what has been done with various specific sensors.

    When you get your next round of questions ready for a new forum thread, add a little more detail about what you want to do. It may be that none of these are what you are looking for. I am making a lot of assumptions.

    Regards,
    RandyP

    Hi Randy,

         Thanks for your reply. I will have more questions, once I work with video systems.
