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 |
