When flattening H in line 102, I get TypeError: order must be str, not int
.
From the documentation a letter must be provided indicating wether to flatten in column-major or row-major style. Which is the correct one?
The np.std() function computes the standard deviation over all the entries of the flattened matrix. So for instance, given an array a = np.array([[1,2],[3,4],[5,6]])
, the std is computed over the 6 entries rather than the 3 points.
I think this line of code in the DLTcalib() function is the correct template to compute the mean distance: err = np.sqrt(np.mean(np.sum((uv2[0:2, :].T - uv)**2, 1))
.
After performing SVD, my V looks like this:

Therefore, creating L will be a division through 0 and the whole matrix can't be computed. Any idea what the problem could be?
