PointNet++ with much better segmentation accuracy, 84.68% mcIoU on shapenet(SSG without normal). - pointnet2-pytorch/README.md at master · voidmomo/pointnet2-pytorch
接下面来看pointnet的pytorch实现,utils下两个训练程序:分类和分割 分类 分类首先调用的是PointNetCls,其定义如下 classPointNetCls(nn.Module):def__init__(self,k=2,feature_transform=False):super(PointNetCls,self).__init__()self.feature_transform=feature_transform# 使用pointNet提取特征# PointNet的主要实现...
