align_image_stack is a command-line tool available in the development version of hugin to align overlapping images to facilitate HDR creation, Exposure blending and extended Depth of Field images.

Usage

align_image_stack [options] input_files

Options: modes of operation

-p file   

Output .pto file (useful for debugging, or further refinement)

-a prefix 

Align images, output as prefix_xxxx.tif

-o output 

Merge images to HDR, generate output.hdr

Options: modifiers

-v        

Verbose, print progress messages

-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

-d

Optimize radial distortion for all images, except for first.

-i

Optimize image center shift for all images, except for first.

-x

Optimize X coordinate of the camera position.

-y

Optimize Y coordinate of the camera position.

-z

Optimize Z coordinate of the camera position. Useful for aligning more distorted images.

-S

Assume stereo images - allow horizontal shift of control points.

-A

Align stereo window - assumes -S.

-P

Align stereo window with pop-out effect - assumes -S.

-C

Auto crop the image to the area covered by all images.

-c num    

Number of control points to create between adjacent images (default: 8)

-l

Assume linear input files

-s scale

Scale down image by 2^scale (default: 1 [2x downsampling]). Scaling down images will improve speed at the cost of accuracy.

-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] )

-h        

Display help.
