Night Time Scanning

Post by Erick0068 »

Good afternoon,

I've had the opportunity to scan outdoor scenes at night and have learned through trial and error that adding artificial light to a scene can be tricky when scanning that scene. Experience has taught me to place the lights quite a distance from the area to be scanned to try and make the light fall off as even as possible.

Can you folks with more experience offer any additional suggestions on how to best manage night time scenes? Do you even bother with artificial light? If so, what tricks have you developed to keep the light from washing out the color images from the scanner.

For background, we're using a FARO Focus x330. Can you believe it, we bought them just a few months before the HDR version came out!

Have a look at this thread here...

Also, I've found that you can have some really great results by using a spotlight and just aim/follow in the direction of the scanner mirror. You would be surprised at how much your scene actually becomes lit.

That would be my preference if I was trying to reach greater distances. Ideally, the spot light would fill the field of view of the single photo taken by the mirror at whatever distance you are trying to reach.

Regards,

Eugene
