How to compare with methods using perspective projection? Ignoring the mpjpe and only comparing pa-mpjpe?

[miraclebiu]

I am a new comer in this field, And I have two questions:
1、When I read the codes in run_metro_bodymesh.py, L396 only gives gt_pose and gt_betas to get the gt_vertices, so the evaluation doesnot include txyz?
2、How to compare with SOTA methods which use perspective projection? As these methods may give txyz for smpl layer to get vertice coords. (Txyz from gt and from prediction may have error and the error contains in the mpjpe) Under such condition, is the mpjpe meaningless, and only the pa-mpjpe is useful?
Many thanks for your kindly response!
