Custom Lens Design
This weekend we assembled the first of the new lenses (the 3D-360 will use 10 of them). The new lens is bright and sharp. We also assembled a variant of the LED Light Engine for military evaluation.
Light Engine Testing
This low power version of the Light Engine is only about 1/20th the intensity of the full system, but that one will not be ready until late February.
Light Beam Projection
The Light Engine produces fairly collimated light.
Partially Illuminated Light Engine
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…
Pattern Projection
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
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…
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…
Feb 2007 Prototype 3.3
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…
