Welcome! We
are working to define, create, extend, and document the full tool chain
required to bring the ability to create, upload, and share high
resolution explorable images at the macro, micro, and nano scales to the
widest audience. While
we work to make the process as easy, intuitive, and efficient as
possible we have setup and made the following devices, software, and
documentation available.
The
project and work presented here builds upon the Global Connections
Project and GigaPan.org at Carnegie Mellon University. For complete
information about GigaPan and its mission, visit the site at http://www.gigapan.org/
What is a Microscopic Gigapixel Image?
A gigapixel image is typically made up of a 2-dimensional mosaic of
images. The images are individually taken to cover the entire subject
area to be photographed and then stitched together to make a seamless
image. For microscopic work, we add a third dimension to the process in order to obtain the full depth of field of an object. For a microscopic gigapixel image,
you may need to take anywhere from 50 images to 50,000 images to get
the detail and resolution you desire. It all depends on the size of your
subject, the camera resolution, and the lens magnification you are
using.
How Do I Make One and What Tools do I Need?
The basic process involves...
1. Capturing the Images. For
the most efficient methods, use an automated motion control device and
camera system, and automation software. Devices and software that we use
are outlined below.
2. Post-Processing the Images.
This involves focus stacking the images, stitching the images, and
rendering a seamless image. Your final image is typically quite large
and may be difficult to manage. But there is a solution for that in step
three. The software and process is outlined in our Open Source Capture Software Page.
3. Uploading the Image to GigaPan.org. This allows you to view and share your imagery with others without the need for a high powered computer or fancy programming.
