  • 结合真实场景图像,用高斯点阵合成新视角。
  • 新视角合成使模型在SSIM、PSNR等指标上显著提升。
  • 适合扩展现实、自动驾驶等需高质量3D重建的场景。

本文系统比较了摄影测量法与高斯点阵技术在三维模型重建和视角合成中的表现。基于真实场景拍摄的图像数据集,分别构建三维模型,并通过结构相似性(SSIM)、峰值信噪比(PSNR)、学习感知图像块相似性(LPIPS)及基于USAF分辨率靶标的lp/mm分辨率进行评估。研究开发了改进版高斯点阵代码库,支持在Blender中生成新相机位姿并渲染高质量新视角,验证其灵活性与潜力。进一步构建包含原始图像与合成新视角的增强数据集,用于训练新摄影测量模型,结果表明合成视角可有效提升三维重建质量。对比分析揭示了两种方法的优势与局限,为扩展现实(XR)、摄影测量及自动驾驶仿真应用提供参考。代码开源:https://github.com/pranavc2255/gaussian-splatting-novel-view-render.git。

原文摘要 · Abstract (English)

In this paper, I present a comprehensive study comparing Photogrammetry and Gaussian Splatting techniques for 3D model reconstruction and view synthesis. I created a dataset of images from a real-world scene and constructed 3D models using both methods. To evaluate the performance, I compared the models using structural similarity index (SSIM), peak signal-to-noise ratio (PSNR), learned perceptual image patch similarity (LPIPS), and lp/mm resolution based on the USAF resolution chart. A significant contribution of this work is the development of a modified Gaussian Splatting repository, which I forked and enhanced to enable rendering images from novel camera poses generated in the Blender environment. This innovation allows for the synthesis of high-quality novel views, showcasing the flexibility and potential of Gaussian Splatting. My investigation extends to an augmented dataset that includes both original ground images and novel views synthesized via Gaussian Splatting. This augmented dataset was employed to generate a new photogrammetry model, which was then compared against the original photogrammetry model created using only the original images. The results demonstrate the efficacy of using Gaussian Splatting to generate novel high-quality views and its potential to improve photogrammetry-based 3D reconstructions. The comparative analysis highlights the strengths and limitations of both approaches, providing valuable information for applications in extended reality (XR), photogrammetry, and autonomous vehicle simulations.
