Here is an early 3D scan from our latest prototype scanner. EARLY is a key word here, because our scanner has only been operational for a couple of weeks. During the last year my team has completely upgraded the scanner hardware including cameras, lenses, chassis, and calibration tools. We have also ported our software from…
Stereo reconstruction works by identifying similar features within two images, and we will use any technique that enhances small features. As a first step in our stereo reconstruction pipeline we currently use bilinear interpolation to rectify/dewarp images. While bilinear interpolation is easy to code and does a good job, there are many other types of interpolation worth considering. The…
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…
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…
