Openstreetcam fisheye removal
I record a lot of my cycling routes using a GoPro Hero 5 black mounted to my bike.
After recording I upload the images (1 images/sec) to openstreetcam.
But the face and car sign detection cannot cope with the fisheye in the GoPro images so I had to remove them before upload.
This is the script I use:
#!/bin/bash MOGRIFY=`which mogrify` if [ $? -eq 1 ]; then echo "you need to install imagemagick" exit 1 fi if [ "$#" -ne 1 ]; then echo "Add folder to process as argument." exit 1 fi source_folder=$1 path=`realpath $1` dest_folder=`dirname $path`/z_fisheye/`basename $1` source_count=`find $source_folder -name \*JPG | wc -l` echo "number of files to process: ${source_count}" if [ -f "${source_folder}/000_fisheye.done" ]; then echo "${source_folder} already processed!" exit fi mkdir -p $dest_folder ( cd $source_folder for photo in *.JPG; do if [ -f "${dest_folder}/${photo}" ]; then echo -n "." else $MOGRIFY -path ${dest_folder} -distort barrel "0 0 -0.2" ${photo} echo -n "." fi done | pv -pte -i0.1 -s${source_count} > /dev/null ) # check if all images from source folder are in dest_folder dest_count=`find $dest_folder -name \*JPG | wc -l` if [[ $source_count == $dest_count ]]; then touch ${source_folder}/000_fisheye.done fi
After all files in a folder are processed a file named
000_fisheye.done will be created in the source folder.This helps finding the folders I can upload to openstreetcam.
