Method Description:
ACDet is a single-stage multi-view fusion 3D object
detection method which consists of a geometric-
attention kernel, a transformer based cross-view
fusion module and an anchor-free detection head.
ACDet addresses the challenge of detecting small
objects with sparse LiDAR points, and improves the
overall accuracy of multi-class 3D object detection.
Parameters:
\lambda_{cls} = \lambda_{loc} = \lambda_{obj} =
\lambda_{dir} = 1.0

Detailed Results

Object detection and orientation estimation results. Results for object detection are given in terms of average precision (AP) and results for joint object detection and orientation estimation are provided in terms of average orientation similarity (AOS).
