@ -4,33 +4,45 @@ exif_rad.py is a simple unix-style cross-platform Python 3 tool which can write
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`.
By now it can parse a .his (CSV) file from a [GeigerLog](https://sourceforge.net/projects/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
* [piexif](https://pypi.org/project/pyexif/): Python module for working with EXIF image data.
## 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.
All sources are matched by their timestamp, so all sources have to be recorded during the same time (and timezone)
## Usage
to-do
```usage: exif_rad.py [-h] [-si SIFACTOR] [-o OUTDIR] CSV Photo [Photo ...]
A tool that writes radiation levels (and optionally geocoordinates) to image
files and extracts the infos from external sources.
positional arguments:
CSV Geiger counter history file in CSV format.
Photo One or multiple photo image files to process.
optional arguments:
-h, --help show this help message and exit
-si SIFACTOR, --sifactor SIFACTOR
Factor to multiply recorded CPM with. (default:
0.0065)
-o OUTDIR, --outdir OUTDIR
Directory to output processed photos (default: .)
```
## 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.
