Lens Analysis Tool and non-symmetrical lens.

[rodbrew]

Hi,

I've got some security camera footage that I'm trying to camera match. It's a system that has a camera inside a 360 degree glass bulb. The bulb seems to be adding an additional warp which doesn't seem symmetrical. I can get close using a Spherical Panoramic camera but it is not quite there. I can take the rendered image into photoshop and using the warp tool get a really good match without much trouble. I can use that same warp on the grid pattern to generate a pattern to use in the lens analysis tool but the resulting profile doesn't seem to work. I assume this is because it's trying to create a symmetrical lens. So my question is is there a way to generate a non-symmetrical lens profile based on a non-symmetrical grid pattern?

I've attached the warped grid pattern.

Thanks,

P.s. I suppose another option is that the footage has been cropped on the left side.

If you can generate an stmap for the distortion in Nuke or a similar tool, you can also use that as a distortion texture directly; this approach can do any distortions including non-symmetric ones.
