摘　　要：点云是一种广泛应用于三维场景表示和处理的数据结构。然而,在真实世界中获取完整且准确的点云数据仍具有挑战性。因此,点云填充技术得到广泛研究,旨在通过生成缺失的点云数据来提升点云的完整性。本文提出一种基于生成对抗网络(GAN)的点云填充方法,该方法利用生成器网络生成缺失区域的点云,并通过判别器网络对其真实性进行评估。实验结果表明,本文方法可处理各种大小和形状的点云孔洞,并生成无缝衔接的修复结果。Point clouds serve as a fundamental data structure extensively employed for representing and processing 3D environments.Nevertheless,acquiring complete and precise point cloud data in the real world remains a formidable challenge.Consequently,extensive research efforts have been dedicated to point cloud inpainting techniques,with the primary objective of enhancing the comprehensiveness of point clouds by generating missing data.This paper introduces an innovative point cloud inpainting method,harnessing the power of Generative Adversarial Networks(GAN).The proposed approach utilizes a generator network to intelligently synthesize point cloud data within regions of absence,subsequently subjecting it to scrutiny through a discriminator network to assess its authenticity.Notably,our method’s experimental outcomes demonstrate its remarkable ability to adeptly address point cloud voids of diverse sizes and shapes,culminating in the seamless integration of inpainting regions with the existing data.In conclusion,this research represents a significant stride towards overcoming the challenges associated with incomplete point cloud data,offering promising prospects for various applications reliant on accurate 3D scene representation and analysis.
