3d camera with TMS320DM series

Paulo Valentim

Hello! I am newbie at this... I want to build a small 3d based IP camera. I have two 1.3MP cameras which output BT.656

My original idea is to combine the 2 outputs of these cameras into an FPGA to make one single (side by side) BT.656 stream and feed that stream into a TI DSP.

Then I would like to have the DSP stream this through EThernet to process the depth map in a PC.

Questions:

1. Can I bypass the FPGA somehow and combine the two BT.656 inputs inside the DSP?

2. Is it true I can process the depth map information inside a DSP?!? Any DSP has the horsepower for this?

3. If the answer to 2) is YES, then can I stream out through Ethernet one of the incoming video streams together with the depth map information?

Thanks!!!

Hi,

Thanks for your post.

In general, FPGA is intended for additional video coprocessing options, so it is not recommended to bypass the same for better system design.

I don't think, FPGA can be bypassed since the system architecture is designed to must pass through FPGA in order to get compatible BT.656/BT1120 input format. I think, the video decoder drivers are tied to FPGA in order to generate BT.656/BT1120 data compatible to standard input format.

May be, you could refer the below e2e posts for more details on the above:

Let me check on your question2, as of now, I am not sure on this.

Thanks & regards,
