Compiler/TDA2E: STITCHING CODE IN TDA2XX SURROUND VIEW

Hello,

Apologies for the delayed response. Do you have access to the Vision SDK? Stitching happens as a part of rendering.

Hi Hemand,

Yes, I have  access to the vision SDK..i just want to know  the algorithm behind the stitched video.

Hi , I have access to the Vision SDK. Do u know the algorithm behind the stitched video and the corresponding code in SDK ?

Hello Sebinraj,

Please refer to this document:

http://www.ti.com/lit/wp/spry270a/spry270a.pdf

This explains how Surround View works. I recommend going through the document. GPU stitches video frames based on a mesh table that is generated based on camera calibration data. Please note that stitching happens as a part of GPU rendering in a single step. I will assign this ticket to someone who can help you with code structure.

Hi, 

Can you please share any document or any Code explanation for the above, as i needed it for fine tuning the stitched view i am getting now because in that one view is enlarged while comparing with other three.

Hi

Please open the "Index" HTML file & you can easily navigate the required document.

Hi,

When i ran the surround view use case no.3, i got a stitched output on my screen, but in that, one of the view (front_view) is enlarged in a disproportionate scale compared to the other three. Can anyone help me to know, what might be the reason behind this and resolving this issue. 

Thanks in Advance..

Hi,

Have you done any changes? apart from the use-guide changes

Which SDK version are you using?

Thanks

Gaviraju

Hi Gaviraju,

I have build the SDK as per the user guide and did'nt make any other changes. I am using PROCESSOR_SDK_VISION_03_08_00_00. Also can we change the individual ratio of the each views in the stitched output view and which part of the code underlies this functionality ?? As i saw that blending LUT and geometric LUT makes the output stitched view , by what criteria these both LUT 's are produced? Can i change this value to produce the required output ?

Thanks in Advance

Hi Sebinraj,

Can you confirm if you have the surround video algo source code. i.e. Can you please check if source is included in \vision_sdk\algorithms\surroundview\algorithmSrc\src

Regards, Sujith

Hi Sujith,

Can you please specify the correct path. In my SDK when i checked the algorithmSrc folder , only include folder was present didnt find any src folder. 

Hi Sebinraj,

It looks like you don't have the source code of the Algo. A typical VisionSDK release will not include algo source code. You will have to talk to FAE who is helping you.

Hi Sujith,

Then from where do i find algo source code ??...and what actually is FAE ?..

Hi 

Can anyone provide me the source code of the Algo... Now I have  PROCESSOR_SDK_VISION_03_08_00_00..

Thanks in advance

Hi Sebinraj,

The algorithm source code is not released. As advised earlier, please contact TI Sales / FAE's
