Why are pairs with a relative rotation greater than 10 degrees filtered out? #92

I'm a bit confused about this. Is 10 degrees too small a threshold? Does this mean that if my shooting angle rotates more than 10 degrees, the matching will fail?

Hi, "10 degrees" is with respect to the error. That say, if you have a pair of image with a relative rotation of 30 degrees, and the estimated relative rotation is 35, then it will be kept, but if the estimated relative rotation is 45 degrees, then it will be filtered.
