Hi everyone,
I'm trying to use your Distance Estimator interface, I executed "python3.6 DistanceEstimatorApplication.py" in a terminal, and I got the following error:

Traceback (most recent call last):
File "DistanceEstimatorApplication.py", line 13, in
from PIL import ImageTk, Image
ModuleNotFoundError: No module named 'PIL'

I would appreciate if you can help me to solve this problem.

In DistanceEstimatorApplication.py you import NavigationToolbar2TkAgg but this is no longer available in matplotlib - the current name is NavigationToolbar2Tk. I use the following:

try:
    # NavigationToolbar2TkAgg was deprecated in matplotlib 2.2 and is no
    # longer present in v3.0 - so a version test would also be possible.
    from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg, NavigationToolbar2TkAgg
except ImportError:
    from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg, NavigationToolbar2Tk
except:
    raise

This is also regarding DistanceEstimatorApplication.py - when showing the PDFs it calls plot_image which uses the show() option to FigureCanvasTkAgg - this is no longer (not sure which matplotlib version) supported and .draw should be used instead. I use:

        if hasattr(dataPlot, 'show'):
            # Deprecated version
            dataPlot.show()
        elif hasattr(dataPlot, 'draw'):
            dataPlot.draw()
        else:
            # Maybe print a warning?
            return
