A question in PGD (Probabilistic and Geometric Depth: Detecting Objects in Perspective) ? #2456

In Paper, in the equation 4, what is the difference between d and z ? z is the depth in camera coordinate, and what is the phisical meaning of d ? In equation 3, you said that bx,by and bz denote the baseline with respect to the reference camer, so what is the phisical meaning of bx, by, bz ?
