That won't be very accurate. Not designed that way. Turn your lens until it stops, and then look at the focused distance scale. It won't be at infinity. Hard to beat actually focusing it.
Well, that's how I did it (with some manual focus lenses, without an infinity mark and/or distance scale). However, it's true that some lenses can "go" a bit beyond the infinity, but the small aperture values (high numbers) should be keeping the infinity within the DoF.
Where do I find the focused distance scale?
The 18-55 VR doesn't have this scale. Not sure about the 55-200, but I don't think it does either. That's what makes finding "infinity" a bit more challenging.

Correct. Challenging but possible. I have both lenses, and focusing at the night can be a real pain.. I usually go to infinity, then backup justthismuch. These lenses are somewhat picky at the far end of their range. If time permits, I'll even pull the card, and plug it into the laptop to see where I am. But the more you use them, and understand their quirks, it's easier it is to dial in where you can be very close. I'm having much better luck with my 35mm 1.8.
