transformation matrix in the feature space has much higher dimension than the spatial transform matrix, which greatly increases the difficulty of optimization. 对于特征空间的alignment network,由于特征空间维度比较高,因此直接生成的alignment matrix会维度特别大,不好优化,因此这里需要加个loss约束一下。 add a ...

【摘要】 本文分析基于深度学习的3D点云分类和分割的网络。 1)PointNet是直接对点云进行处理的,它对输入点云中的每一个点,学习其对应的空间编码,之后再利用所有点的特征得到一个全局的点云特征。Pointnet提取的全局特征能够很好地完成分类任务,但局部特征提取能力较差,这使得它很难对复杂场景进行分析。 2)PointNet++...
