What is Gaussian Splatting?


The Gaussian Splatting (3DGS) technique is transforming the representation of 3D environments by modeling scenes using Gaussian representations that integrate geometry and properties such as color and opacity. Unlike traditional methods based on point clouds or meshes, this approach uses optimized splats, allowing for continuous representation and achieving more faithful reconstructions and more efficient rendering.

The implementation of Gaussian Splatting constitutes a significant advance in the digitalization of environments, by integrating high photometric fidelity with computational efficiency in the processing of graphic data. Unlike traditional methods, this technique allows for the reconstruction of complex scenes with astonishing precision in critical details such as transparencies, reflections, and thin structures, eliminating visual distortions common in classic photography.

Its main benefit lies in its real-time rendering capability, which allows navigating high-resolution digital twins with complete fluidity on conventional hardware. Currently, its use is key in strategic sectors, from industrial inspection to drone photogrammetry:


 

Reality Capture: Gaussian Splatting in Lixel Cyber Color

XGRIDS, thanks to its Lixel line capture systems which integrate LiDAR sensors and RGB cameras, allows generating hybrid models of high precision and realism. Through the use of Lixel Cyber Color software, it is possible to represent environments with high density and visual consistency, optimizing processing in 3DGS and resulting in continuous scenes with a very high level of realism and representativeness.

This technology has various applications in different areas of industry, including:

  • Digital Twins and Industrial Inspection
  • Architecture, Real Estate
  • Cultural Heritage
  • Virtual and Augmented Reality

 

Drones and UAS: Gaussian Splatting in DJI Terra

In recent years, DJI Terra has established itself as one of the most advanced software solutions for 2D and 3D reconstruction. Its ability to process complex data flows from drones, whether through high-resolution photogrammetric sensors or LiDAR systems, has positioned it as a fundamental tool in workflows that demand an accurate representation of captured surfaces. 


With the launch of DJI Terra v5.0, native 3D reconstruction based on Gaussian Splatting has been integrated, allowing visualizations with a level of fidelity and performance that surpasses the traditional limitations of point clouds and 3DMesh. 

 

What are the outstanding benefits of DJI Gaussian Splatting?:
  • Improved color restoration, with greater visual fidelity
  • More realistic representation of vegetation
  • Detailed reconstruction of fine structures
  • Faithful representation of static water surfaces, transparencies, and reflections in glass
