Linear autocalibration does not work. #7

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago

What steps will reproduce the problem?
1. Modify the homography H_real in line 104 of autocalibration_test.cc so
that it is different from the identity.
2. Run the autocalibration_test.

What is the expected output? What do you see instead?
The test fails because of a bug in the autocalibration code.  The computed
homography does not seem to be a correct metric update.

I've fixed the problem.  The transformation from projective to euclidean was not
computed in the right way.  The test now works for a random H_real.  We need to 
test
with real data now.
