3d detection for orientation estimation
Jumponthemoon opened this issue · comments
In the code of ddd sample,i saw the ground truth of orientation is constructed by the alpha.
I did some research about alpha and rotation_y in the label file.Seems like the alpha is for local yaw,rotation_y is for global yaw.
So i reckon this operation for alpha is to recover the global yaw from the local yaw.If so,why not directly use the rotation_y?
Or if i get this operation wrong.Please help,thanks!
