What's the cameraMatrix related to ? #4

Closed jingmouren closed 4 years ago

jingmouren commented 4 years ago

It's related to the training data set, so when matching other images, using the same matrix as the example. Or related to the testing time, so it can only be used to matching images that knows the matrix and must be provided by the user?

Hi~I don't know exactly which "matrix" you refer to.

jingmouren commented 4 years ago

I mean the K0 and K1 camera matrix used in computing the inline matched point and the corresponding angle in the notebook.

liuyuan-pal commented 4 years ago

They are the intrinsic matrices of two images which are used in the computation of the pose. Matching doesn't require these two matrices.
