The Steuart Systems photorealistic 3D scanner uses hardware & software to produce 3D models, but how good is our software? We used the ETH 3D benchmark to evaluate it. We were hoping to be in the top 10% of the 116 entries from around the world, and the March 31 2022 benchmark result put us at #1….
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…
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…
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…
Since 2003 I’ve been refining the patented 3D-360: an omnidirectional stereoscopic camera system. In this 2007 picture, prototype 3.2 is being upgraded to Proto-3.3. Currently (December 2008) a much-improved Proto-4B is being built with an ETA of April 2009.
