PointFusion: Deep Sensor Fusion for 3D Bounding Box Estimation

Xu, Danfei, Anguelov, Dragomir, Jain, Ashesh

Understand

We present PointFusion, a generic 3D object detection method that leverages both image and 3D point cloud information.

  • Unlike existing methods that either use multi-stage pipelines or hold sensor and dataset-specific assumptions, PointFusion is conceptually simple and application-agnostic.
  • The image data and the raw point cloud data are independently processed by a CNN and a PointNet architecture, respectively.
  • The resulting outputs are then combined by a novel fusion network, which predicts multiple 3D box hypotheses and their confidences, using the input 3D points as spatial anchors.
