- Download Example Files (from above) and extract to folder
- Open Hugin and import source files
- Set the lens parameters (Focal Length 8.7mm, Crop 1.5), Full Frame Fisheye for images taken around at 90 degree yaw intervals, Circular Fisheye for the Zenith and Nadir images. Assign lenses so that the the first 4 images are Lens 0, Zenith is Lens 1, Nadir is Lens 2.
- Mask each image. For the first 4 images, mask off the tripod/panohead and any other extraneous objects, also the corners. Set crop circles for the Zenith and Nadir.
- Now add control points to each overlapping pair of images. Concentrate on placing a good spread of points along the centre of the overlapping regions. There is no need for placing points away from the likely seam lines.
- Add vertical control points/lines so that the pano will be level
- Start optimising the position, gradually including field of view, barrel, then everything except translation. Periodically check for control points with large errors, correct if necessary. Use the Custom Optimisation options to fine tune the process.
- Check that the geometry of the assembly is satisfactory using the Preview Window.
- Start on optimising exposure. Choose Low Dynamic Range, then Custom. Deselect optimisation of Vignetting and Camera Response. Optimise just the exposure values, the the Red and Blue Multipliers.
- Finally, stitch and export the panorama in your preferred format.
You try stitching the image using the automatic mode in Hugin, or in any other panoramic programme of your choice.
