In asmall cave tucked away south of Paris, scientists believe they’ve stumbled upon something extraordinary: what might be the oldest known 3D map created by humans. Carved into stone some 20,000 ...

Abstract: This paper proposes a non-invasive way to detect the antenna type from its radiation patterns to cross-validate its proper functioning. Here, the radiation pattern of three types of antennas ...

Abstract: Due to the difficulty of annotating the 3D LiDAR data of autonomous driving, an efficient unsupervised 3D representation learning method is important. In this paper, we design the Triangle ...
