I would like to buy a Passive 3D Stereo Monitor for Geospatial in order to view stereoscopic digital and make analysis and reconnaissance of historical aerial imagery. (stereo pairs)
Any suggestion of any system to view digital in my pc the following stereoapirs?
I've got an old tabletop stereo viewer that stands on legs. It's set up for a distance of 4" from hardcopy photos. Each eye has to focus on a separate image to get the stereo effect. If you get out to a normal viewing distance of 18" or so from a computer screen, that's hard to accomplish. At that distance each eye will focus on both images.
I've tried this viewer on some old stereo photos of people, buildings, scenery, etc. These were popular 80 or 100 years ago, and a lot of them were sold.
They make stereo viewers for virtual-reality images on a smartphone, again at a viewing distance of 4" or 5". If you could get something like that, you could transfer the stereo pair to the phone. The spacing between the centers of the two images might have to be adjusted. From what I've seen in playing around with these old photos, the spacing should be close to the distance between the pupils of your eyes.
@rplumb314 Untill now I was using sokkia ms 27 stereoscope with 8x zoom, I done this with hardcopy stereopairs for my city for a project.
But now they provide me only digital stereopairs.
Can you post a photo to understand better waht you have done?
I looked at the MS 27 online. It's much better than the little 1950s table-top model that I have because it has more magnification.
Do you still have the MS 27? If so, you could blow up the screenshot you posted, cut the images apart, print hard copies, and view them in the same way that you have been doing.
@rplumb314 No its not possible!
Hard copies has not the same quality as the digital one scanned from the film! Even digital or print them from the film!
I understand you to say that the digital images are of good quality. Is that correct? If you blow them up to large size on screen, can you see details well?
If the digital images are of good quality, you could try printing them on photo paper rather than plain paper.
If the digital images are not of good quality, you will need to ask for better ones.
