Partially Illuminated Light Engine

December 4th, 2008 No comments

The latest version of the omnidirectional stereoscopic camera system needs LOTS of light, so we made a Light Engine. Here’s a picture of it in action. It is VERY bright. I took this picture by pointing the camera in the general direction of the Light Engine while looking the other way.

If you happen to stare into the light engine with one eye…..
Use remaning good eye to find the power switch & turn it off.

Pattern Projection

October 25th, 2008 No comments

I spend most of my day trying to make noise-free images, so it is no suprise that I am also interested in the opposite. Our new camera for Proto-4B can capture nearly 10 frames per second for hours. Now that we have the speed I need we will tune the exposure routines (next week’s work).

Prototype 4A Scan

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

June 14th, 2008 No comments

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.
