Survey of 3D Reconstruction Techniques Based on 3D Gaussian Splatting

The 3D reconstruction technology based on 3D Gaussian splatting (3D GS), launched at the end of 2023, has outstanding advantages in both the quality of new view synthesis and the speed of scene rendering compared to mainstream traditional algorithms in the field. This paper analyzes the essence of the 3D GS technology and its huge potential for application, comprehensively sorting out the application of 3D GS-based 3D reconstruction technology in the field of visual SLAM (simultaneous localization and mapping), dynamic scene reconstruction, generative AI (artificial intelligence), and autonomous driving. Finally, the potential and technological iteration trend of 3D GS technology are discussed from the perspectives of scientific research output and practical implementation.
