Method Description:
CPD (Commonsense Prototype-based Detector) is a
high-performance unsupervised 3D object detection
framework. CPD first constructs Commonsense
Prototype (CProto) characterized by high-quality
bounding box and dense points, based on
commonsense intuition. Subsequently, CPD refines
the low-quality pseudo-labels by leveraging the
size prior from CProto. Furthermore, CPD enhances
the detection accuracy of sparsely scanned objects
by the geometric knowledge from CProto.
Parameters:
NAN

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).
