Step 6Stitch!
You're finally ready to create your final panoramic image. Switch to the Stitcher tab; I'll explain all the options below.
The first two options are the projection and field of view. Both of these can also be changed from the preview window, where you can see graphically how they affect the panorama.
Hugin can generate images in a number of different projections, and different scenes look best in different projections. The rectilinear projection is the same projection that an ideal normal camera lens produces (and the same as you see with your eyes). Rectilinear projections, by definition, represent straight lines in the scene as straight lines on the image. Rectangular structures like buildings will appear the same way they do in real life, but objects far away from the center of the image will be stretched to much larger than normal. This will usually destroy your image if it's wider than 90ý or 100ý, so it's best for narrow or tall panoramas.
Wider panoramas look best using either a cylindrical or equirectangular (spherical) projection. Both of these projections avoid distorting horizontal distances away from the center of the image, but will turn horizontal structures above or below the vertical center into arcs and bubbles.
Field of view controls how wide an angle will be shown in the output image. The "Calculate Field of View" button will find the smallest view that includes every image. Anything larger than this just wastes memory, disk space, and processing time, so use the sliders in the preview window to crop your panorama to just the section you need.
Next is the canvas size. This is the size of the final output image, in pixels. The values given by "Calculate Optimal Size" represent the largest size possible without stretching the source images beyond their original sizes. You can use a larger size of course, but you'll just be creating redundant pixels. Larger panoramas take more time to generate, use more memory, and create larger files on your disk, so start small to get an idea of what kind of size your hardware (and patience) can handle.
Hugin can output (actually, instruct other programs to output) many different types of images in different formats from a single panorama project. Most of the time you simply want the "blended panorama," which calls nona to remap your images into the new projection, and uses enblend to smooth out the seams.
Finally, you can pick the format and compression options for the final image.
Once everything is ready, click "Stitch now!" Hugin will prompt for a filename to write the output to, and start crunching your source images into a beautiful panorama. Several windows may appear during the process, talking about laplacian pyramids, exposure layers, blend masks, and whatnot. When everything is finished, you should have a nice big image file in the directory you specified earlier.
