question about cameras extrinsics, is the plane generated from z_pitch_yaw better ?

[rangerToby]

i'm trying to use my own dataset to train hdmapnet, and my cameras are not horizontal（differ from nusenes)，so i want to know that is the plane generated from z_pitch_yaw better ? @simonyilunw @hangzhaomit @Mrmoore98 @liqi0126
