Step 2Overview
This instructable will cover the following steps for taking panoramas:
1. Taking source photos. All images have to be taken with the camera in the same position and using the same exposure settings (unless you're using exposure blending).
2. Identify control points. Pairs of control points are used to figure out how the images will fit together. Each control point pair identifies either two points in different images that refer to the same point in the scene, or two points in the same image that should be a horizontal or vertical line in the final image. Control points can be placed by hand or automatically using autopano.
3. Optimize the panorama. The PToptimizer program uses the control points to calculate which position (expressed as pitch, roll, and yaw angles) each image corresponds to, as well as how much distortion was introduced by the camera lens.
4. Preview, edit control points, optimize again, GOTO 10. The first result won't be perfect. You may need to add, delete, or move control points, add guides to keep horizontal and vertical structures at the right orientation, select which projection you want to use, or adjust the field of view to include only the parts of your images that you want.
5. Stitch the image. This is where the real work happens. The stitcher program takes the previously calculated image positions and remaps each pixel of the input images from its original projection to where it should be in the final panorama. The output will be either a single merged image or a series of images, each containing pixels from exactly one source image, to be blended later.
6. Blend the stitched images to look more pretty. Some extra processing is usually needed on the stitched output to clean up seams where images don't perfectly meet or other irregularities. Enblend and enfuse are automated tools hugin uses for this step, or you can do it by hand in an image editor like GIMP.
