Nick sat patiently while he was scanned with Proto-4A.
3 shots merged with XFuse: an OSX front end to Enfuse/Enblend. This might be my new HDR tool of choice.

Lens Testing with Laser

I’m using a laser from Home Depot to roughly characterize a lens for Prototype 4B of the 3D-360 scanner. The lens looks like HAL from 2001.
Google Sketchup Basecamp

From June 11 to 13 Google hosted a 3-day training called SketchUp Basecamp. About 400 people from all over the world all gathered to learn about the 3D visualization techniques of SketchUp and how to integrate the 3D models into Google Earth. We spent most of our time on this patio and in the buildings that you see.
Inspired by Google’s global perspective, I decided to make a Google-centric version of a “Google Earth.” I stiched 18 images together to make a spherical panorama, and then warped the image to form a globe. This is a first draft, and I plan to post a better HDR version without the tripod and shadow once I get back home.
The stitching errors have been removed, and HDR & tone mapping have improved the details. There will probably be a V6 with a few more tweaks. A little more sky would be nice, and there are some HDR artifacts in the lower left.
54 shot panoramic HDR.

Self portrait in the calibration lab made during a test of new software. When this picture was taken the new code was in a user hostile pre-alpha mode. I like the noise and banding effect even though it was caused by a bug that we fixed the next day.
The system is now producing low-noise 5MP color images that are over 16 bits deep. Unfortunately the lenses are now the weak link. Once the custom lenses are built and installed (April 2009) I will begin posting the results.

This hodgepodge of cameras, epoxy, and even duct tape was was used to develop 3D scanning software. After the research (late 2007) it was dissasembled and 7 of the 8 Canon 5Ds (I kept one =:-) were sold on E-bay. A much improved Prototype 4B with 10 custom cameras and lenses will allow a new phase of development in early 2009.
