Re-timing images without GPS data

Posted by mycae-gmx on 6 January 2014 in English (English)

I had the problem whereby images from my camera did not write the time in the EXIF data. This means I can't geo-correlate my tracks with my camera data.

Thanks to exiv2, and some crappy bash scripting, something like this works for setting the time from the timestamp (which is fine, as long as the camera time is OK). This is very budget, but it works well enough.

 #!/bin/bash

 #Set the exif timestamp using the file creation date
 for i in *jpg
 do
    THISDATE=`ls -l --time-style="+%Y:%m:%d %H:%M:%S" $i | awk '{print $6 " "$7}'`
    exiv2 -M"set Exif.Photo.DateTimeOriginal ${THISDATE}" $i
 done
