How to get "sparse" 3d facial landmarks #103

Open tkzky opened 3 years ago

tkzky commented 3 years ago

Thank you for your code. I'd like to know how can I get "sparse" 3D landmark coordinates? Like (x,y,z) And does the Z coordinate represent the depth information of the landmarks? Looking forward to your reply!

I also have this problem, do you solve it ?

tkzky commented 2 years ago

I don't solve it, what about you?

But the z is not the real depth, since 3DDFA_V2 adopts the weak-perspective projection (or scaled orthogonal projection).
