How can I magnify ≤1mm objects onto a display for under $200?
2020年8月18日 · A stereo microscope is probably the best tool for the job - unlike a realistic camera-based solution it maintains binocular vision and depth perception. The one I use in work can divert the light from one eyepiece to a DSLR; I tried hooking it up to a monitor once, and it was unhelpful (though this was partly an issue of dynamic range with a ...
File formats for stereoscopic 3D images - Photography Stack …
2019年7月10日 · With stereographic images, proper alignment of the left and right images is very important to avoid eye strain. For example, your eyes will not be happy if an object in the left image is a bit higher than the right. Imagine your left eye trying to look up while your right eye is looking down. Misaligned 3D images cause literal headaches.

2015年4月29日 · Use a Fresnel Lens at the light source to distribute light more evenly. This may already be built into the microscope. Use a convex-plano lens at the sensor. This will affect magnification, sharpness, and focus. Use flat-field correction software. This is a digital version of the film technique @AlanMarcus describes.
What is the difference between a 3D camera and a stereo camera?
2019年7月19日 · No, "3D camera" is not the same as "stereo camera". A stereo camera takes two images at the same time (either via two separate lens/sensor assemblies, or via a mirror system to split the frame of a single assembly into two views). Both images these cameras produce are regular images; they don't make one for the image and one for the depth map.
How can I view stereoscopic image pairs without a stereoscope?
2020年10月17日 · This works both with conventional stereo pairs and with multi-image like the Nimslo camera (intended for lenticular stereo prints). The images are pasted into an animated GIF file in a manner that causes them to display for a short time (.2 to .5 seconds per frame works well) in an order that seems to "tilt" the image right to left and back again.

2016年5月5日 · And then you'd have to find some way to duplicate Cardboard Camera's computational ability to create stereo images from a single image, much as 2D-shot movies get 3D-ized. Everybody wants high quality for free and little-to-zero effort, but it's rarely a possibility.

2024年7月21日 · Procure a working light meter. Procure a plastic funnel that will accommodate the meter. The other end of the funnel should be sized to slip over the microscope's eyepiece. Tape frosted plastic sheet over entrance to the light meter. The meter will now read the intensity of the light traversing the microscope.
Is there maximum distance for stereoscopic photography?
The depth information is calculated by comparing two feature points in the two images. The difference in point position is called disparity. In rectified, parallel stereo cameras you end up with a disparity map. This contains all the information for depth calculation, you only need the baseline and focal length of your two cameras. Maths
What open source software for auto-alignment of photographs?
2011年6月5日 · Now the images are ready to be, for instance, enfused: enfuse aligned_*.tif If you prefer the graphical interface, or you want to align only partially overlapping images (like in panoramas), then use Hugin itself, it is a very powerful and …
How to make spherical (360) panoramic image with 2:1 aspect ratio?
Spherical panoramas have a 2:1 aspect ratio because the field-of-view is 360° x 180°. You obviously need enough photos to cover the whole surrounding. If you use stitching software, then you need to have some overlap between images and will take slightly more images than enough to cover exactly the 360°.
