My 9 year old son was asking whether we could scan ourselves and the house, and so, having the equipment at home before visiting one of our field sites I thought "why not?". Scanning in a tight, built-up environment like this illustrates some interesting aspects of the scanner geometry and the camera properties.
|RGB (top) and distance-coloured scan (bottom) of rear of house, and me and Rudi.|
The detail you can see always amazes me, and this is far from the highest resolution the scanner is capable of (100 times finer) and the image resolution is low to get it under the blogger 300k image size limit.

The lower view shows the scanner shadow behind our figures, with my very characteristic (apparently) ears showing prominently. It can be hard for people who don't know how the scanner works to understand how you can view from any point, even where the scanner can't see due to shadowing/occlusion.

Next time I've got the scanner at home I might try and scan with targets to do a registered point cloud.
