1. 2D-projection error

2D-projection error measures the average distance between the 2D projections in the image space of the 3D model points, transformed using the ground-truth pose and the predicted pose. The pose estimate is considered to be correct if it is within a selected threshold. 2D-Proj denotes the percentage of correctly estimated poses using a 2D Projection Error threshold set to 5 pixels. For symmetric objects, the 2D projection error is computed against all possible ground truth poses, and the lowest value is used.

2D-projection error 是测量 3D 模型点图像空间中 2D 投影之间的平均距离,使用 ground truth 姿势和预测姿势进行转换。 如果姿态估计在选定的阈值内,则认为姿态估计是正确的。 2D-Proj 表示使用 2D 投影误差阈值设置为 5 像素的正确估计姿势的百分比。 对于对称对象,2D 投影误差是针对所有可能的 ground truth姿态计算的,并使用最小值。

2. ADD

paper:Model based training, detection and pose estimation of texture-less 3D objects in heavily cluttered scenes

ADD measures the average distance between the 3D model points transformed using the ground-truth pose and the predicted pose.
For ADD metric, a pose is regarded as correct if the average distance of model points is less than 10% of the model diameter.

ADD测量使用 ground truth 姿势和预测姿势转换的 3D 模型点之间的平均距离。对于 ADD 度量,如果模型点的平均距离小于模型直径的 10%,则认为姿势正确

A D D = 1 m ∑ x ∈ M ∣ ∣ ( R x + t ) − ( R ^ x + t ^ ) ∣ ∣ ADD = \frac{1}{m}\sum_{x\in M}||(Rx+t)-(\hat Rx+\hat t)|| ADD=m1x∈M∑∣∣(Rx+t)−(R^x+t^)∣∣

Visible Surface Discrepancy (VSD) is an ambiguityinvariant metric that depends on the visible surface, which can account for the symmetry better.
