adding meta data to images #17

Open SammyRamone opened 6 years ago

SammyRamone commented 6 years ago

Some meta is very interesting for some approaches of computer vision Most importantly and wide spread is the camera angle and height at the moment of recording. Furthermore the aperture of the camera as well as maybe some camera calibration values would be interesting These values should be stored in a standardized format (e.g. euler angles with a defined 0° position) on the server but it has to be possible to export them into different values (e.g. other orientations, or representation as quaternion) Additionally, there should be the possibility to attach arbitrary meta data to images and image sets for information which go beyond camera angle and height.

We could parse the description in the metadata of png images. It would be very easy to use JSON as metadata format because we could use the JSONB-Field of the database to access the values. We should define a fixed format (name and measurement unit) for some frequently and commonly used params like robot position or which camera of an NAO was used.

Hi @NFiedler , is there any updates on this? Else I think I can create a pull request for this. =)

NFiedler commented 5 years ago

That would be tremendously helpful! Feel free to contact me (git@nfiedler.de) with questions or to discuss. Or ask/discuss right here. :)
