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.
As you can see in the above example, the resulting image may have an irregular border,
depending on the amount and position of overlap, and the warping required to
achieve alignment. If necessary, the border can be straightened with a Crop node.
