align_image_stack − Align overlapping images for HDR or focus stack creation
align_image_stack [options] input files
align_image_stack is used for the alignment of slightly misaligned images. When several differently exposed images are taken in the process of creating a High Dynamic Range image, the images are not perfectly aligned, and the quality of the HDR image created will suffer from this. align_image_stack uses the tools available to hugin to optimize the roll, pitch and yaw, as well as some parameters of the lens geometry, to align the images
Modes of operation:
−p file
Output .pto file (useful for debugging, or further refinement)
−a prefix
Output aligned images as prefix_xxxx.tif
−o output
Align images and merge them to HDR , generate output.hdr
Modifiers:
−v |
Verbose, print progress messages. Repeat for higher verbosity |
||
−e |
Assume input images are full frame fish eye (default: rectilinear) |
−t num
Remove all control points with an error higher than num pixels (default: 3)
−f HFOV
Approximate horizontal field of view of input images, use if EXIF info not complete
−m |
Optimize field of view for all images, except for first. Useful for aligning focus stacks with slightly different magnification. |
−c num
Number of control points (per grid) to create between adjacent images (default: 8)
−l |
Assume linear input files |
−s scale
Scale down image by 2^scale (default: 1 [2x downsampling])
−g gsize
Break image into a rectangular grid (gsize x gsize) and attempt to find num control points in each section (default: 5 [5x5 grid])
