Hi, thanks for sharing. Could you tell me how did you calculate the camera parameters, such as fl and c_p?

lck1201 commented 5 years ago

@XiumeiChen Hi, for original integral pose regression, we use the camera parameters provided by HM3.6M. For ECCV challenge, we project & back-project between 3D and 2D based on weak perspective.

@lck1201 thank you. But I still have difficult with getting the camera params using H3.6m official tool. Does fl means the focal length, i.e. obj.f in H36MCamera.m, and obj.k for c_p?

lck1201 commented 5 years ago

@XiumeiChen Yes, fl = focal length. And what do you mean obj.f, obj.k? Could you post some samples?

XiumeiChen commented 5 years ago

@lck1201 I'm confused with getting fl and c_p using the official tool of H3.6m. It seems the camera params are in the class "H36MCamera.m", then which params stand for fl and c_p? image

lck1201 commented 5 years ago

@XiumeiChen It's clear obj.f = focal length= fl, and obj.c = center = c_p. Please refer to wiki for more camera parameter knowledge.

Thank you.
