We use a novel grouping mechanism – sliding frustums to aggregate local point-wise features for use of a subsequent In this work, we propose a novel method termed Frustum ConvNet (F-ConvNet) for amodal 3D object detection from point clouds. Although the point-wise feature extraction and the segment-wise extraction processes are related, since the later methods resort to point-wise feature extractors, segmentation solutions when applied to volumetric point cloud representations tend to improve efficiency and inference time of the whole 3D object detection model, due to the data volume Frustum ConvNet: Sliding Frustums to Aggregate Local Point-Wise Features for Amodal 3D Object Detection . Including the first resolution, we have in total four kinds of resolutions in KITTI dataset. We first divide each point into a separate perspective voxel and project the voxel onto the image feature maps. In this paper, we propose a novel and effective Multi-Level Fusion network, named as MLF-DET, for high-performance cross-modal 3D object DETection, which integrates both the feature-level fusion and decision-level fusion to fully utilize the This paper aims at developing a faster and a more accurate solution to the amodal 3D object detection problem for indoor scenes. Given 2D region proposals in a RGB image, our In this paper, we propose a novel method called Frustum 3DNet (F-3DNet) for 3D object detection from point clouds in IoT. 5: Normalization of point coordinates for final refinement.
