• Abstract: The paper proposes a light-weighted stereo frustums matching module for 3D objection detection. The proposed framework takes advantage of a high-performance 2D detector and a point cloud segmentation network to regress 3D bounding boxes for autonomous driving vehicles. Instead of performing traditional stereo matching to compute disparities, the module directly takes the 2D proposals from both the left and the right views as input. Based on the epipolar constraints recovered from the well-calibrated stereo cameras, we propose four matching algorithms to search for the best match for each proposal between the stereo image pairs. Each matching pair proposes a segmentation of the scene which is then fed into a 3D bounding box regression network. Results of extensive experiments on KITTI dataset demonstrate that the proposed Siamese pipeline outperforms the state-of-the-art stereo-based 3D bounding box regression methods.

  Main challenge of monocular 3D object detection is the accurate localization of 3D center. We propose a stage-wise approach, which combines the information flow from 2D-to-3D and 3D-to-2D. Our method, named as MonoXiver, is generic and can be easily adapted to any backbone monocular 3D detectors.

• Stereo CenterNet based 3D Object Detection for Autonomous Driving [2.508414661327797]
  We propose a 3D object detection method using geometric information in stereo images, called Stereo CenterNet. Stereo CenterNet predicts the four semantic key points of the 3D bounding box of the object in space and uses 2D left right boxes, 3D dimension, orientation and key points to restore the bounding box of the object in the 3D space. Experiments conducted on the KITTI dataset show that our method achieves the best speed-accuracy trade-off compared with the state-of-the-art methods based on stereo geometry.

• Reinforced Axial Refinement Network for Monocular 3D Object Detection [160.34246529816085]
  Monocular 3D object detection aims to extract the 3D position and properties of objects from a 2D input image. Conventional approaches sample 3D bounding boxes from the space and infer the relationship between the target object and each of them, however, the probability of effective samples is relatively small in the 3D space. We propose to start with an initial prediction and refine it gradually towards the ground truth, with only one 3d parameter changed in each step. This requires designing a policy which gets a reward after several steps, and thus we adopt reinforcement learning to optimize it.
