Pointnet等模型评价结果

一、Pointnet评价结果

1、Performance(classification)

Download alignment ModelNet here and save in data/modelnet40_normal_resampled/.

Model	Accuracy
PointNet (Official)	89.2
PointNet2 (Official)	91.9
PointNet (Pytorch without normal)	90.6
PointNet (Pytorch with normal)	91.4
PointNet2_SSG (Pytorch without normal)	92.2
PointNet2_SSG (Pytorch with normal)	92.4
PointNet2_MSG (Pytorch with normal)	92.8

注：pointnet（pytorch）版源码在modelnet40数据集上的官方预测结果是103个批次预测结果的均值89.2%；
pointnet论文中的class_acc为40个不同类别预测结果的均值86.2%、instance_acc对应的是103个批次预测结果的均值accuracy overall为89.2%。
建议：有关实验数据集可从tensorflow、pytorch和keras官网中加载。

2、Performance(Part Segmentation)

Download alignment ShapeNet here and save in data/shapenetcore_partanno_segmentation_benchmark_v0_normal/.

Model	Inctance avg IoU	Class avg IoU
PointNet (Official)	83.7	80.4
PointNet2 (Official)	85.1	81.9
PointNet (Pytorch)	84.3	81.1
PointNet2_SSG (Pytorch)	84.9	81.8
PointNet2_MSG (Pytorch)	85.4	82.5

3、Performance on sub-points of raw dataset (processed by official PointNet Link)

Download 3D indoor parsing dataset (S3DIS) here and save in data/Stanford3dDataset_v1.2_Aligned_Version/.

Model	Class avg IoU
PointNet (Official)	41.1
PointNet (Pytorch)	48.9
PointNet2 (Official)	N/A
PointNet2_ssg (Pytorch)	53.2
