conv_num的公式里，用红字标出来的‘+3’，这是代码里提到的，pointnet_sa_module首先进行sample_and_group运算，来看代码做了什么： sample_and_group(npoint..., radius, nsample, xyz, points, knn=False, use_xyz=True): ''' Input: npoint: int32 radius: float32..., 3) TF tensor new_points: (batch_size, npoint, nsample, 3+channel) TF tensor idx: (batch_size, npoint..., nsample) TF tensor, indices of local points as in ndataset points grouped_xyz: (batch_size, npoint,..., xyz)) # (batch_size, npoint, 3) if knn: _,idx = knn_point(nsample, xyz, new_xyz) else: idx, pts_cnt
l1_xyz, l1_points, l1_indices = pointnet_sa_module(l0_xyz, l0_points, npoint=512, radius=0.2, nsample...scope='layer1', use_nchw=True) l2_xyz, l2_points, l2_indices = pointnet_sa_module(l1_xyz, l1_points, npoint...NCHW data format for conv2d, which is usually faster than NHWC format Return: new_xyz: (batch_size, npoint..., 3) TF tensor new_points: (batch_size, npoint, mlp[-1] or mlp2[-1]) TF tensor idx: (batch_size, npoint..., nsample, 1) new_points *= weights # (batch_size, npoint, nsample, mlp[-1]) new_points = tf.reduce_sum

这个方法会绘制由 nPoint 个线段定义的多边形，其中前 nPoint - 1 个线段是 1 ≤ i ≤ 时从 (xPoints[i - 1], yPoints[i - 1]) 到 (xPoints[
