This post compares our latest 3D results with results from November 2012 (3 months ago). Our 3D models are generated by processing pairs of 2D images, and the same 2D images that were processed in the November post have been processed again. The only difference between the two 3D models is that new version was…
We spent the summer of 2012 enhancing our 3D scanner. The 3D scan below with 3.5 million points shows that the system can now produce high-resolution 3D models. Some improvement was the result of integrating code from the open source projects Point Cloud Library & OpenCV, but the largest improvement came from camera recalibration. Why…
The cameras are finally calibrated, and the communications and power systems are installed and working. Now I can finally begin producing scans to test and fine tune the software. Today I scanned part of the lab, and the animated GIF illustrates the 3D nature of the scan. When producing a 3D model, multiple perspectives must…
The Prototype-4.x family of 3D-360s is based on a camera that we have been developing for over a year. While several areas of enhancement are still left to be implemented, the new camera is ready to be compared against the Canon 5D. Prototype-3 used eight Canon 5Ds, and the new camera in Prototype-4 needs to…
We spent the last year designing and building a camera and software that can capture images with pixels that are 16-bits deep. It isn’t easy to view these images since most tools expect 8-bit images, so the following routine is used to squeeze the 65,536 values in the 16-bit image down to the 256 values…
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).
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…
