can you open qgis without plugin?that is a mistake of qgis, not the plugin

[kikislater]

Yes of course, I use it every day ...
How to debug it ? I use others plugins, this one is the only one making qgis crashing !

[All4Gis]

I will try to reproduce it in the same version of OS that you

can you add the complete log message?

[kikislater]

There is another version in testing repository. I will test it tomorrow and on another installation.

[kikislater]

Ok it works on another installation. It seems to be opencv. I will tell you when I will find

[All4Gis]

I'm glad ! Could you send me a PR, to add your installation notes for this OS? So we add it to the readme so that other users don't have problems in the future.Thanks

[kikislater]

Yes ! Let me find the problem first. I'm on this second setup today. May be at the end of the day ...
I'm also interested in this plugin and curious about how you will compute footprint, is this implemented at this time ? I use an adjusted process from postgis cookbook to do it : https://github.com/giscan/Postgis-footprint

[All4Gis]

the methods are CornerEstimationWithOffsets and CornerEstimationWithoutOffsets the second is a pure photogrammetric algorithm

[kikislater]

Hum seems perfect ! I think I will use your plugin.
Mind you use auto srtm download ? there is a python lib to do it : 30m worldwide => http://elevation.bopen.eu/en/stable/quickstart.html

[All4Gis]

this is nice! I didn't know that library! Could you make your changes in the code and send me PR?

[kikislater]

Yes but not for the next days. When I will have more time ;-)

[All4Gis]

No worries!take your time!thanks

[kikislater]

Ok so just removing opencv installed from pip work and prevent qgis crashing. OpenCV package distribution already include python wrapper, so I think pip package and archlinux package are in conflict.
Where do I put PR ? How to edit readthedocs ?

Archlinux installation :

pacman -S qgis python-matplotlib opencv ffmpeg 
pip install homography

FFmpeg path

ffmpeg = "/usr/bin/"
ffprobe = "/usr/bin/"

[All4Gis]

Ah okey!change the readme.md!for example create a new block "installation notes". Use any text editor

[All4Gis]

I have updated the readme with your information!
I consider as result the issue,okey?

[kikislater]

Hum, no ! I have updated to qgis 3.2.2 and now it install opencv version automatically in local pip repository I think. But for others things, it's ok !

[All4Gis]

ok! then close if your consider solved
