jameszzn / fisheye_distortion_correction

Algorithm that performs correction of image distortion, causes by fisheye lens

Program specification

Fisheye lens distortion correction, with a specific lens specification file. Algorithm of correction is based on equisolid mapping function. Input image have to be yuv image Input and output image, have to be in data folder! Lens specification file, have to be in data folder!

Lens Specification file

Lens Spec file have to be csv file, with just two column usage.

Organisation description:

• First field, represent focal length of camera in milimeteres,
• Second field, represent sensor pixel pitch in mm,
• Third field, represent scaling factor, that can be combinated with focal length.
• After three fields, every in separate row, next two columns represents parameters that are unique for every lens. That columns are field angle / hieght space in mm.

Run program:

ldc_tool.out -i ../data/image.YUV -o ../data/image_COPY.YUV -p ../data/LensSpec.csv -w 1920 -h 1080 -f 1

ldc_tool.out -i ../data/image.YUV -o ../data/image_COPY.YUV -p ../data/LensSpec.csv -w 1920 -h 1080 -f 2
