hough ellipse fit inaccurate?

[Arno Dietz]

Hm I don't know. Do you have the file "true_coords.pickle" in the 
directory? So I think the simplest way is to post the true coordinates here 
so you can just copy and paste instead of loading it.

true_coords = np.float32([[116.16552734, 56.91558838],
[119.50671387, 50.36520386],
