This 3D model includes alignment errors……. and we know how to fix them. Our objective is to develop an automatic 3D model creation system, and we know from experience that the errors will get smaller as our calibration process is refined. Below is a description of how this model was made using images from Proto-4F…
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…
This is the first color image produced by the new camera & lens combination. The bilinear rectification routine that we completed last week was automatically applied to correct chromatic aberration. In the future bicubic interpolation will make the image even sharper. The original 16-bit image had levels and curves adjusted in Photoshop, and the result was converted to…
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…
