filtering photo for high qualitty run

[ronan]

Hi,

When running in batch, i want to run a first low quality dem,
and then before running a high quality run I like to remove all photo which are not fully inside a selected polygon define from a shapefile.

using photoscan module, I found the way to get the foot print of the camera on my low quality DEM.
now I like to disable for my high quality run all photo where the foot print does not intersect my predefined shapefile polygon.
 
I understand you can import shapefile with  chunk.importShapes
but then I do not know how to create a polygon from my 4 foot print corners, and test its intersection with the polygon of my shapefile.
Is there any photoscan module which has the same function as the shapely module?

Thanks for your help
Ronan

Hello Ronan,

In the following thread you can find the script that creates shape for each camera footprint:
http://www.agisoft.com/forum/index.php?topic=6662.msg33020#msg33020

So you may need to create the script that is generating the shape footprints, checking if they are inside the "master shape" and disable the cameras that have the footprints outside the area of interest.

Hi Alexey,
thanks for the reply.
is there any tools within the photoscan environment that can be used to deal with shape/contour/polygon?
For example in other project i have been using shapely.
Thanks
Ronan

Hello Ronan,

The vertices of the shapes are stored as a list - each element is vector with the coordinate information.

You can try to install additional Python module for PhotoScan Python using pip. Which OS you are using?

[ronan]

that would be interesting
I am on xubuntu 16.04
how do you use pip in the photoscan env.
Cheers,
Ronan

Hello Ronan,

you can use the following:

Code: [Select]

photoscan-pro/python/bin/python3.5 -m pip install module_name

thanks
I have the following error when running pip

Hello ronan,

It seems that you might need to install libssl 0.9.8 before using pip install in PhotoScan 1.3:

Code: [Select]

wget http://snapshot.debian.org/archive/debian/20110406T213352Z/pool/main/o/openssl098/libssl0.9.8_0.9.8o-7_amd64.deb
sudo dpkg -i libssl0.9.8_0.9.8o-7_amd64.deb
