Table 2 Average IoU, precision of distance (PD) and relative distance error of the closest 2.5D anchors to GTs (BB and distance) in Pascal3D+ TV dataset

From: Distance estimation with 2.5D anchors and its application to robot navigation

2.5D anchor Avg. \(\mathbf {IoU}\) Avg. \(\mathbf {E}_\text {dist}\) PD (without regression)
Fixed depth, \(z = 0\) 0.45 1.0 0.0
Fixed depth, \(z = \bar{z}\) 0.45 0.39 0.29
Perspective anchor, \(\alpha =3\) 0.45 0.26 0.50
Perspective anchor, \(\alpha =5\) 0.45 0.27 0.49
Perspective anchor, \(\alpha =10\) 0.45 0.33 0.35
