Point cloud classification

Introduction

Classification, detection and segmentation of unordered 3D point sets i.e. point clouds is a core problem in computer vision. This example implements the seminal point cloud deep learning paper PointNet (Qi et al., 2017). For a detailed intoduction on PointNet see this blog post.

Setup

If using colab first install trimesh with !pip install trimesh.

import os
import glob
import trimesh
import numpy as np
from tensorflow import data as tf_data
from keras import ops
import keras
from keras import layers
from matplotlib import pyplot as plt

keras.utils.set_random_seed(seed=42)

Load dataset

We use the ModelNet10 model dataset, the smaller 10 class version of the ModelNet40 dataset. First download the data:

DATA_DIR = keras.utils.get_file(
    "modelnet.zip",
    "http://3dvision.princeton.edu/projects/2014/3DShapeNets/ModelNet10.zip",
    extract=True,
)
DATA_DIR = os.path.join(os.path.dirname(DATA_DIR), "ModelNet10")

We can use the trimesh package to read and visualize the .off mesh files.

mesh = trimesh.load(os.path.join(DATA_DIR, "chair/train/chair_0001.off"))
mesh.show()

To convert a mesh file to a point cloud we first need to sample points on the mesh surface. .sample() performs a uniform random sampling. Here we sample at 2048 locations and visualize in matplotlib.

points = mesh.sample(2048)

fig = plt.figure(figsize=(5, 5))
ax = fig.add_subplot(111, projection="3d")
ax.scatter(points[:, 0], points[:, 1], points[:, 2])
ax.set_axis_off()
plt.show()

To generate a tf.data.Dataset() we need to first parse through the ModelNet data folders. Each mesh is loaded and sampled into a point cloud before being added to a standard python list and converted to a numpy array. We also store the current enumerate index value as the object label and use a dictionary to recall this later.

def parse_dataset(num_points=2048):
    train_points = []
    train_labels = []
    test_points = []
    test_labels = []
    class_map = {}
    folders = glob.glob(os.path.join(DATA_DIR, "[!README]*"))

    for i, folder in enumerate(folders):
        print("processing class: {}".format(os.path.basename(folder)))
        # store folder name with ID so we can retrieve later
        class_map[i] = folder.split("/")[-1]
        # gather all files
        train_files = glob.glob(os.path.join(folder, "train/*"))
        test_files = glob.glob(os.path.join(folder, "test/*"))

        for f in train_files:
            train_points.append(trimesh.load(f).sample(num_points))
            train_labels.append(i)

        for f in test_files:
            test_points.append(trimesh.load(f).sample(num_points))
            test_labels.append(i)

    return (
        np.array(train_points),
        np.array(test_points),
        np.array(train_labels),
        np.array(test_labels),
        class_map,
    )

Set the number of points to sample and batch size and parse the dataset. This can take ~5minutes to complete.

NUM_POINTS = 2048
NUM_CLASSES = 10
BATCH_SIZE = 32

train_points, test_points, train_labels, test_labels, CLASS_MAP = parse_dataset(
    NUM_POINTS
)

Our data can now be read into a tf.data.Dataset() object. We set the shuffle buffer size to the entire size of the dataset as prior to this the data is ordered by class. Data augmentation is important when working with point cloud data. We create a augmentation function to jitter and shuffle the train dataset.

def augment(points, label):
    # jitter points
    points += keras.random.uniform(points.shape, -0.005, 0.005, dtype="float64")
    # shuffle points
    points = keras.random.shuffle(points)
    return points, label


train_size = 0.8
dataset = tf_data.Dataset.from_tensor_slices((train_points, train_labels))
test_dataset = tf_data.Dataset.from_tensor_slices((test_points, test_labels))
train_dataset_size = int(len(dataset) * train_size)

dataset = dataset.shuffle(len(train_points)).map(augment)
test_dataset = test_dataset.shuffle(len(test_points)).batch(BATCH_SIZE)

train_dataset = dataset.take(train_dataset_size).batch(BATCH_SIZE)
validation_dataset = dataset.skip(train_dataset_size).batch(BATCH_SIZE)

Build a model

Each convolution and fully-connected layer (with exception for end layers) consists of Convolution / Dense -> Batch Normalization -> ReLU Activation.

def conv_bn(x, filters):
    x = layers.Conv1D(filters, kernel_size=1, padding="valid")(x)
    x = layers.BatchNormalization(momentum=0.0)(x)
    return layers.Activation("relu")(x)


def dense_bn(x, filters):
    x = layers.Dense(filters)(x)
    x = layers.BatchNormalization(momentum=0.0)(x)
    return layers.Activation("relu")(x)

PointNet consists of two core components. The primary MLP network, and the transformer net (T-net). The T-net aims to learn an affine transformation matrix by its own mini network. The T-net is used twice. The first time to transform the input features (n, 3) into a canonical representation. The second is an affine transformation for alignment in feature space (n, 3). As per the original paper we constrain the transformation to be close to an orthogonal matrix (i.e. ||X*X^T - I|| = 0).

class OrthogonalRegularizer(keras.regularizers.Regularizer):
    def __init__(self, num_features, l2reg=0.001):
        self.num_features = num_features
        self.l2reg = l2reg
        self.eye = ops.eye(num_features)

    def __call__(self, x):
        x = ops.reshape(x, (-1, self.num_features, self.num_features))
        xxt = ops.tensordot(x, x, axes=(2, 2))
        xxt = ops.reshape(xxt, (-1, self.num_features, self.num_features))
        return ops.sum(self.l2reg * ops.square(xxt - self.eye))

We can then define a general function to build T-net layers.

def tnet(inputs, num_features):
    # Initialise bias as the identity matrix
    bias = keras.initializers.Constant(np.eye(num_features).flatten())
    reg = OrthogonalRegularizer(num_features)

    x = conv_bn(inputs, 32)
    x = conv_bn(x, 64)
    x = conv_bn(x, 512)
    x = layers.GlobalMaxPooling1D()(x)
    x = dense_bn(x, 256)
    x = dense_bn(x, 128)
    x = layers.Dense(
        num_features * num_features,
        kernel_initializer="zeros",
        bias_initializer=bias,
        activity_regularizer=reg,
    )(x)
    feat_T = layers.Reshape((num_features, num_features))(x)
    # Apply affine transformation to input features
    return layers.Dot(axes=(2, 1))([inputs, feat_T])

The main network can be then implemented in the same manner where the t-net mini models can be dropped in a layers in the graph. Here we replicate the network architecture published in the original paper but with half the number of weights at each layer as we are using the smaller 10 class ModelNet dataset.

inputs = keras.Input(shape=(NUM_POINTS, 3))

x = tnet(inputs, 3)
x = conv_bn(x, 32)
x = conv_bn(x, 32)
x = tnet(x, 32)
x = conv_bn(x, 32)
x = conv_bn(x, 64)
x = conv_bn(x, 512)
x = layers.GlobalMaxPooling1D()(x)
x = dense_bn(x, 256)
x = layers.Dropout(0.3)(x)
x = dense_bn(x, 128)
x = layers.Dropout(0.3)(x)

outputs = layers.Dense(NUM_CLASSES, activation="softmax")(x)

model = keras.Model(inputs=inputs, outputs=outputs, name="pointnet")
model.summary()

Model: "pointnet"
