How can I remove Photos based on Image quality with script

[Milderinne]

Hello,

I would like to ask if there is any possibility to remove photos based on the calculated image quality with python scripting?
Do I understand it right, that I calculate image quality like this:

Code: [Select]

chunk1.estimateImageQuality()
If not, please tell me how to do it right and how to access these calculated values to disable images which have a poor quality.

Thanks in advance!

Hello Milderinne,

Using the following code you can calculate and access the quality value for the first camera in the chunk:

Code: [Select]

camera = chunk.cameras[0]
chunk.estimateImageQuality([camera])
quality = float(camera.photo.meta['Image/Quality'])

Hello Alexey,

that was fast.
Thank you.
But how do I know use that image quality to disable certain images lower a specific value?

Hello Milderinne,

You can use something like the following:

Code: [Select]

threshold = 0.3

if quality < threshold:
    camera.enabled = False

Thank you so much! I will try that out tomorrow!

Hello Alexey!
It worked perfect 

Doing more scripting of course another question just popped out.
How can I print out the maximum reprojection error in my logfile?

Code: [Select]

MaxReprojectErr = ???
outputLog.write('Starting calculate reprojection errorr: %s\n'%time.asctime())
outputLog.write('Max reprojection error for %s = %s\n'%(chunk1.label, MaxReprojectErr))

Would be great if you could help me figure that out!

Hello Milderinne,

Here I've posted the script that estimates reprojection error for each camera and also the average value:

Hello Alexey,

thank you for forwarding me there. I did not find that before.
