Can't understand the angle trained in network

Open sdukaka opened this issue 8 years ago • 5 comments

In data_processing.py, 43-45 lines shows how to get theta than trianed, but i don't understand the equal in file. theat_train should be rotation_ray - angle_obj, could you explain your method?

Hi @sdukaka,

It just orientates +pi/2, and it will subtract pi/2 in the final output.

But this angel is only the degree between camera and object center and what we want to use in training stage is the difference of theta_ray - rotation_y(the obj's own rotation)

Yes, the outputs of network are 3D dimensions and observation angle of the object.

@sdukaka Hi, have you figured out what the angle exactly means? I can't understand it at all. Could you please help me understand what we should train for?

I think the angle what we should train for is between camera and object center.
