DepthSplat

DepthSplat is an innovative AI framework that reconstructs detailed 3D scenes from only a few input images.

DepthSplat is an innovative AI framework that reconstructs detailed 3D scenes from only a few input images, merging Gaussian splatting with depth estimation to deliver high-quality depth predictions and view synthesis. By integrating these methods, DepthSplat enables a unique cross-task interaction: improved depth estimation enhances the quality of 3D scene rendering, while Gaussian splatting serves as an unsupervised pre-training objective to boost depth prediction accuracy.

DepthSplat is designed to handle both single- and multi-view depth estimation, making it adaptable to diverse scenarios, even with limited visual input. Leveraging pre-trained monocular depth features and a feature-matching architecture, DepthSplat produces realistic 3D reconstructions with scale-consistent depth predictions, delivering state-of-the-art results on benchmarks like ScanNet, RealEstate10K, and DL3DV. It is particularly effective on challenging datasets, outperforming other methods on complex real-world scenes and large-scale environments.

Key Features:

  • 3D Scene Reconstruction: Generates high-quality 3D scenes from a few images with precise depth and view synthesis.

  • Gaussian Splatting and Depth Estimation: Connects Gaussian splatting with depth estimation, improving both rendering quality and depth accuracy.

  • Unsupervised Depth Pre-Training: Uses Gaussian splatting as a pre-training method, enhancing performance on depth estimation tasks without labeled data.

  • Scale-Consistent Depth Predictions: Maintains depth scale aligned with camera translation, essential for accurate 3D reconstructions.

  • High Performance Across Datasets: Achieves top results on ScanNet, RealEstate10K, DL3DV, and performs exceptionally well on TartanAir and KITTI datasets.

Use Cases:

  • 3D Modeling and Visualization: Ideal for creating detailed 3D models from limited input images for use in gaming, VR, and AR.

  • Architecture and Real Estate: Generates accurate 3D renderings of spaces from a small set of images, useful for virtual tours and property visualization.

  • Robotics and Autonomous Systems: Enhances environment understanding with reliable 3D scene reconstructions, aiding navigation and spatial awareness.

DepthSplat offers a groundbreaking approach to 3D scene reconstruction, setting new standards in depth estimation and view synthesis with a training-free, high-performance model suitable for both research and practical applications.
