Hugin calibrate lens

Hugin Calibrate Lens is a tool for lens calibration using the straight line method.

Simple workflow:

• Load images ("add" opens a file browser)

• Check focal length and crop factor (calibrate lens tries to read them from the EXIF data)

• Select "Find lines" to detect the straight lines

• Choose the lens parameters to optimise, then select "Optimize"

• "Save lens" to save optimised lens parameters into file for use in hugin

Calibrate_lens_gui is installed when you install hugin.
