Compiler/TDA2HG: How do I do perspective transformation for a image on TDA2x?

Hi,

Are you trying to do in vision SDK?

Thanks

Gaviraju

Yes, I have a board of TDA2HGx, and I use vision SDK 3.3.

Thanks

Sorry, my vision SDK'version is 03_06

You could have to use some DSP kernels to do it. There is no HW module to do perspective transform.

Sorry, I'm a rookie on TI.

So could you please explain what HW module is?

And how do I use the DSP kernels to do something, there are some documents for this?

Thanks and Best Wishes!

Hello,

You mean according to the GPU in my chip and then go to its official manual?

This requires going to the GPU's official website, not TI's, right？

Hope to get your recovery,

thank you.

Hi,

Can you please check if GPU is available in your device? If it is, then i think GPU can do perspective transform.

If not, then you need to write some DSP kernels to do this operations.

Sorry, 

I found that the GPU of the chip I used was SGX544，but I've never used it.

I only used DSP to process the image.

And I've only used some simple USECASES running on the RTOS.

Are there any GPU's documents I can refer to? Please.

thank you.

Hi Yu Liu,

GPU is supported on Linux and exposed using OpenGL interface. So you could refer to OpenGL documentation to do perspective transformation.
