How to extract models from Burnout Paradise?

I don’t have the PC Version. I only have the PS3 Version
I do want extract the models from there, but the problem is how?

Umm…Anyone?

should allow you to edit/view the iso on the pc

Thanks that should help a bit, but how exactly I am going to use it?
And also how do I get the PS3 iso to my PC?
