Gaussian expression has become the most high-profile research direction in the field of 3D scene reconstruction and drawing. In just one year, the quality and performance of Gaussian expression in 3D reconstruction and drawing have been fully proven in academia and industry, and have begun to be applied in important research fields such as SLAM and digital human. At the same time, a large number of research works are being carried out and published, including but not limited to further improving Gaussian expressions to improve their drawing speed, quality and accuracy of geometric representations, as well as the application of Gaussian expressions in high-fidelity digital human modeling and driving, real-time 3D reconstruction, reverse rendering, large-scale scene reconstruction and other aspects. In this context, this forum intends to share reports and discuss from multiple dimensions such as the theory, technology and application of Gaussian expressions, so as to further promote the development of 3D reconstruction theory and technology based on Gaussian expressions.

Title: 3D Gaussian Reconstruction and Generation of Dynamic Scenes
Abstract:3D Gaussian point cloud rendering (Guassian Splatting) has emerged as a new differentiable rendering technology. Compared with NeRF, it has gained a lot of attention in recent years due to its higher rendering quality, faster rendering speed, and more compatibility with traditional rendering pipelines. With the advantages of Guassian Splatting in 3D scene expression and rendering, this paper introduces the research work of the reporter in dynamic 3D reconstruction, dynamic 3D editing, and digital human generation. The report will also discuss the future development trend of 3D representation based on the current video generation model.

Title: Real-time Gaussian SLAM: Real-time high-fidelity 3D reconstruction of large indoor scenes
Abstract:Real-time reconstruction of 3D scenes is a key supporting technology in the fields of augmented reality, unmanned driving, and low-altitude economy. The traditional reconstruction technology has high geometric accuracy, but cannot present a high-fidelity appearance. The NeRF-based reconstruction technology has high computational cost and high memory consumption, making it difficult to achieve real-time reconstruction. In this report, I will introduce the preliminary exploration of the research group in the direction of real-time Gaussian SLAM. We propose the first real-time Gaussian SLAM system, which simultaneously obtains high-quality geometry, high-fidelity appearance, and accurate camera pose during the scanning process. The system reconstruction performance reaches real-time, the memory consumption is low, and it supports real-time high-fidelity 3D reconstruction of large-scale indoor scenes.

Title: High-Fidelity Virtual Human: From Modeling, Driving to Generation and Editing
Abstract:In recent years, the representation methods represented by NeRF and 3D Gaussian have made great breakthroughs in the reconstruction of people, objects and scenes due to their strong fitting expression ability and differentiability. In addition to modeling, the multimodal drive of digital humans, the editing and control of appearance and emotion are equally important. In this report, I will introduce the research work of the research group in the rapid reconstruction of virtual digital humans, physics-based movement and clothing drives, and multimodal digital human editing.

Title: Geometrically accurate 3D reconstruction based on 2DGS and its application
Abstract:Three-dimensional Gaussian splash (3DGS) has made revolutionary progress in 3D reconstruction, achieving high-quality new perspective synthesis and fast rendering speed. However, due to the multi-view inconsistencies of the 3D Gaussian scatters, 3DGS cannot accurately represent the surface. We propose a novel method based on 2D Gaussian splash (2DGS) to model and reconstruct geometrically accurate optical radiation fields from multi-view images. At our core, we depicted 3D objects with a set of 2D directional plane Gaussian disks and introduced a perspecular-accurate 2D splash process. We have proven the effectiveness of 2DGS in several applications such as 4D reconstruction, human reconstruction, and scene editing.
