Autonomous driving is advancing rapidly, fueled by improvements in sensor technology and artificial intelligence (AI). Lidar-captured point clouds are crucial for these systems, offering precise spatial data and detailed environmental representations. Data are essential for developing and validating robust AI-based systems. However, obtaining real-world data is costly, and capturing specific scenarios, especially dangerous or rare cases, is impractical. As a result, synthetic point cloud generation is emerging as a promising alternative. Despite increasing interest and techniques, there is no comprehensive survey on synthetic point cloud generation for autonomous driving. This article addresses this gap by exploring the challenges in generating synthetic point clouds, outlining the methods used, and cataloging available datasets. This survey aims to provide a foundational understanding of the state of the art in synthetic point cloud generation, promoting further research in this critical area of autonomous driving technology.
