TDA3: Maximum concurrently run-able applications and stereo front camera

Santhosh Muralidharan

Part Number: TDA3


Hi,

   We are currently evaluating TDA3x for our product idea. It would be great, if someone could throw some light on the questions below. 

   Here, there is a demo on TDA3x that runs the following applications concurrently, 

   1) Pedestrian detection

   2) Cyclist detection

   3) Vehicle detection

   4) Distance calculation 

   5) Traffic Sign Recognition

   6) Land Departure warning

While running 6 applications, the TDA3 also has some headroom (DSP1 30 % free, DSP2 54% free,  EVE1 25% free, ) for more applications.

Questions:

1) Using the available headroom, Is it also possible to add Driver monitoring related algorithms (for attentiveness and drowsiness) along with the above listed 6 applications? 

2) The above given demo is simulating a monocular front camera. What would be the impact on performance, if we had to use a stereo front camera and running the same set of above listed 6 applications on TDA3x? 

Thank you.

Regards,

Santhosh

    Hi Santhosh,

    I have forwarded your question to a SW architecture expert.

    Yes, you can add any new Algos provided you manage the DSP/EVE loading

    2) The above given demo is simulating a monocular front camera. What would be the impact on performance, if we had to use a stereo front camera and running the same set of above listed 6 applications on TDA3x?
    currently we perform all the Front camera analystics on a single camera stream @15-20fps and are not designed to work with stero streams. you can try running these algos on both left and right camera, but then FPS might reduce to half.

    Hi Shiju.

    Thanks for your inputs. 

      >>> you can try running these algos on both left and right camera, but then FPS might reduce to half.

    I was under the impression that in a stereo front camera based system, the 2nd camera will be used ONLY to calculate a more accurate  distance-to-object.

    Please correct if my understanding is wrong. 

    Do we have to run all the algos on both the Left and Right cameras, or only the distance-to-object calculation related algos alone? 

    For example:

    Stereo L: Object detection, distance-to-object 

    Stereo R: distance-to-object

    Hi
    Oh, ok. I am not an expert in this stereo processing.
    If you are running FC algos only on one of the camera (say, second one), then you can expect to get the same VSDK performance
