# radiation tagger
|
|
|
|
exif_rad.py is a simple unix-style cross-platform Python 3 tool which can write certain tags to an image file.
|
|
|
|
It can scan a couple of images, extract their Exif-tags, and compare the `DateTimeOriginal` with other sources.
|
|
|
|
By now it can parse a .his (CSV) file from a GeigerLog file export and calculate the radiation in µS/h using the factor in `SIFACTOR`.
|
|
|
|
It then creates a `UserComment` Exif tag with the actual measured radiation at the time the photo has been taken.
|
|
|
|
## Dependencies
|
|
Right now it depends on the following Python 3 libraries:
|
|
|
|
* PIL (core library)
|
|
* datetime (core library)
|
|
* Image (core library)
|
|
* piexif
|
|
* gpxpy
|
|
|
|
## Requirements
|
|
* GeigerCounter log file in csv format as it is being exported by the software GeigerLog. Such files look like this: `149654, 2020-02-27 05:12:42, 13.0, 0.0`
|
|
* A bunch of images (jpg, cr2, etc.) with its time of creation stored in `DateTimeOriginal`
|
|
* A gpx track
|
|
|
|
All sources are matched by their timestamp, so all sources have to be recorded during the same time.
|
|
|
|
## Usage
|
|
|
|
to-do
|
|
|
|
## future possibilities
|
|
|
|
* In the future it should also be able to do the same with a gpx-file to extract geolocations and to write them into the appropiate Exif-fields.
|
|
* It might get interactive help and command line argument processing.
|
|
* It might get a setup.py if I want to waste my time on it.
|
|
* I might want to get rid of the requirement to use a bloated GUI application to download the history data off the geigercounter. There must be a neat working command line tool.
