Epipolar curves in Python #134

Closed yosefm closed 7 years ago

yosefm commented 7 years ago

This is mostly a new epipolar curve drawer, not using the epi_* functions in the library, but reimplementing the algorithm in a more general way. It works on the pixel coordinates rather than staying in the flat metric coordinates. One can calculate any number of points along the curve, thus observing the effect of camera distortions more directly.

I've also included a true unit test - the C test for epipolar lines is just a regression test. We should consider backporting it, but not now, ok?

(This PR is the last I need for getting my replacement of the PyPTV main screen to be distributable.)
