Re: Distortion parameters from vision sensor?

Hello,

If the checkerboard texture was applied on a plane.

I think the possible approximate way around knowing the real simulation size of the grid in the checkerboard texture is to create a primitive shape (like a cuboid or a plane) with a known size. Then, adjust the primitive shape by trial and error, until it fits one of the grids. The size of the cuboid or plane can be assumed to be the actual size of the grid in simulation.

Check out this repository for an example of a scene.

Maybe you didn't understand me or I didn't make it clear. As far as I know, there is no guarantee that the imported texture will exactly cover my shape. So setting the shape size cannot equal setting the texture size. So, how to determine the texture size?Any suggestions would be appreciated.
Thanks in advance.
