Comparing Steering angle

[Raclk]

Hey Guys,

i want to compare the steering angle of the pretrained modell and my own trained modell. But i don´t know how i can do this. It would be nice if someone could help me with this issue.

I tried to calculate the steering angle of the pretrained modell but its always the false result.
If someone knows how to calculate the steering angle then pls help me out. I really need it for a projekt.
