Stereoscopic Reconstruction "In the Round".

Written by Charles Douglas Wehner

Continued from page 1

This is not very good stereo. For much of our daily lives we talk to each other at a range of about six feet - and our eyes are quite capable of resolvingrepparttar DEPTH of each others features to better than an inch at this range.

Even if we have images that are NOT onrepparttar 113259 point standard - 72 points torepparttar 113260 inch - but sharper, such as 300 or 600 dots per inch, we have problems. How do we manipulate so many dots?

Furthermore, we would really like to find a way of SUGGESTINGrepparttar 113261 presence of edges BETWEENrepparttar 113262 dots - a system of ANTI-ALIASING.

With this in mind, I have created a small program called MoveR. It movesrepparttar 113263 dots torepparttar 113264 RIGHT, and does so in steps of one sixteenth of a dot. Thus, a white dot against a black background is capable of becoming one sixteenth darker whilstrepparttar 113265 neighbouring dot becomes one sixteenth of peak white brighter.

So dots can BLEND from one torepparttar 113266 next, and foolrepparttar 113267 eye into believing that it can perceive depths at six feet to within about a sixteenth of an inch.

A special image has to be constructed to definerepparttar 113268 amount to right shift. This is known asrepparttar 113269 Z-AXIS file, and it complementsrepparttar 113270 XY file. With X, Y and Z fully specifiedrepparttar 113271 entire three dimensions have been defined.

You have to make your own Z-AXIS file. After all, stereoscopic reconstruction is an ART. A machine cannot do it because a machine cannot INVENTrepparttar 113272 missing data.

However, those who haverepparttar 113273 need to reconstruct "flatties" into 3D will find my free program useful.

You can read about it at ools/mover/index.htm and downloadrepparttar 113274 ZIP file from ools/ .

It was suggested on that web-page that there really ought to be a competition forrepparttar 113275 best stereo "resurrection" of Sir Charles Wheatstone - after all, it was HIS lecture that launched 3D uponrepparttar 113276 world. That suggestion is repeated here. My own early attempts at such reconstruction can be seen on my website - I use Wheatstone asrepparttar 113277 subject.

There is also an anaglyph (red-green) making tool. Other tools can be found at ools/

Charles Douglas Wehner was born in 1944.

He was a technical author in nucleonics, photoelectrics, radar and instrumentation and control. Also a factory manager, and for many years a member of the Stereoscopic Society in London, England.
