Hello Guys,

we working on a project, where we processing images and want to use NVIDIA VPI.
We need to do this type of image conversion:

gray_lane
gray_lane1600×1200 122 KB

remap_lane

Would this be possible with the perspective warp in the Nvidia VPI (vpiSubmitPerspectiveWarp)?
Is there further explanation about the perspective warp? Like how would i define
the parameter const Vpiperspectivetransform xform parameter of the function? In the documentation
there is no explanation or i dont understand exactly the maths behind it :(

Hi,

It looks like a fisheyes correction problem?
If yes, you can find a sample below:
