784 Chapter 26 Transformations, Motion Blur, and AutoAlign
Unlike similar photographic tools, the AutoAlign node works with both stills and image
sequences. As a result, you could film three side-by-side shots of an expanse of action,
and later turn these into a single, extremely wide-angle background plate. Similarly,
you can set a single still image to align with the same image features in a second shot
with camera motion.
Stitching Images Together
When you connect two or three overlapping images or image sequences to the
AutoAlign node, they’re assembled into a single composite panoramic image. The input
images can be either vertically or horizontally oriented—the AutoAlign node
automatically determines the areas of overlap and aligns them appropriately.
Note: The order in which you connect images to the AutoAlign node doesn’t matter;
their position is automatically determined.
For example, if you connect the following three side-by-side shots of a skyline to the
inputs of an AutoAlign node:
The overlapping areas are analyzed, matched, and the images are repositioned and
manipulated to fit together.
