Web2.1 PointNet思想 传统的 卷积神经网络 是对图像像素进行卷积，如果在不同方向将点云数据进行投影，再利用卷积神经网络也能实现分割，但是算法复杂且效果不好。 PointNet考虑的是直接输入点云数据，实现一个端到端的网络。 但是点云数据不同于图像数据，首先是点具有 置换不变性 ，即交换任意点之间的位置，不会对整体造成影响 (不考虑回波和辐射强 … WebPointNet首先通过共享的MLP来提取每个点特征，然后利用池化操作再将所有点的特征合并为一个全局特征向量。 对于分类任务来说，可以直接以此向量作为特征，用MLP进行分类。 对于分割任务来说，需要把点特征与全局特征进行拼接，然后用MLP对每个点进行分类（也就是分配一个语义标签）。 PointNet网络结构 从上面的描述中不难看出，虽然点分类的 …
