Question about angle?

[ilwoonam75]

Sorry to bother you again.

I succeeded training with cube dataset with your help.

And I am trying to train my own dataset.
I want to detect the rotated vehicle.

This time I am little confused with the angle.

I think you use 0 to 90 angle because the cube is square. right?

But because vehicle is rectangle, I think I cannot express the angle between 0 and 90.

So I changed the angle between 0 and 180, and correct the source code to train 0 and 180 angle.

But the mAP doesn't increase at all.

Can you advice me how to train?

I also trained with 180 degrees before I reduced them to 90 for your already mentioned reason.

Did you take a look at this commit?

This was the change from 180 to 90 degrees.

Do you mean that you changed the max angle from 180 to 90 because you got the good result?

[thohemp]

As far as I remember 180 worked out for me, too, but I expected to archieve more stable results with 90 degrees.

Okay. I will try again. Thank you
