In this paper, we present an implicit surface reconstruction method with 3D Gaussian Splatting (3DGS), namely 3DGSR, that allows for accurate intricate details while inheriting the high efficiency and rendering quality of 3DGS. The key insight is to incorporate signed distance field (SDF) within Gaussians modeling, enable alignment joint optimization both SDF Gaussians. To achieve this, design coupling strategies align associate Gaussians, allowing unified enforcing constraints on With...
In this paper, we present an implicit surface reconstruction method with 3D Gaussian Splatting (3DGS), namely 3DGSR, that allows for accurate intricate details while inheriting the high efficiency and rendering quality of 3DGS. The key insight is incorporating signed distance field (SDF) within Gaussians to enable them be aligned jointly optimized. First, introduce a differentiable SDF-to-opacity transformation function converts SDF values into corresponding Gaussians' opacities. This...
Human beings construct perception of space by integrating sparse observations into massively interconnected synapses and neurons, offering a superior parallelism efficiency. Replicating this capability in AI finds wide applications medical imaging, AR/VR, embodied AI, where input data is often computing resources are limited. However, traditional signal reconstruction methods on digital computers face both software hardware challenges. On the front, difficulties arise from storage...
