Stereoscopic Image scanned with Flatbed Scanner
I found pages about stereoscopic scan with flatbed scanner. Most of flatbed scanner using lens has a parallax; it's quiet for scanning flat object such as paper, but it stand out for solid object (3D-object). It's usually undesirable character, but the stereoscopic scan is a way of making good use of parallax.
It's easy to realize complexity object (e.g. parts that mounted on DC/DC converter in reference web page: [Stereoscopic scanning]) on stereoscopic image, while not on `normal' 2D-image. Therefore it's very useful to make stereoscopic image; moreover, it's easy to make it with your flatbed scanner![ How you scan stereoscopic image ]
After making stereoscopic image, look at the image with wall-eyed method or cross-eyed method that needs no special equipments. Wall-eyed method is a way to look at left image with left eye and look at right image with right eye (If you don't be accustomed it, put the screen or paper vertically, between the pictures and between the eyes). Cross-eyed method is a viceversa; way to look at left image with right eye and look at right image with left eye.
Followings are stereoscopic images that I made. But I think they are not so good 3D images. I don't know why whether materials I used are not good, or my scanning way was bad, or another...
Please note that it's not always equal left of the lens to left side of scanner's body. Left/right in above sentense means that of/for the lens (or CCD sensor). Direction for 3D-scanning is usually opposite of scanning document (Or you can judge which is right side by means of pre-scanning result). Refer to right figure about this note.
Some flatbed scanner uses CIS (Contact Image Sensor), and has no lens. This type of scanner has no parallax, therefore it doesn't fit for stereoscopic scan.
