XGRIDS Reconstructs China’s Minning Town as a 6.2 Billion-Gaussian 3D Model

What happened

XGRIDS reconstructed 23.5 square kilometers of Minning Town as a continuous 3D Gaussian model containing 6.2 billion Gaussian ellipsoids, featured in a China Media Group documentary. The project used 186,000 aerial and ground images and 15 billion LiDAR points, collected over seven days; reconstruction reached centimeter-level geometric accuracy with error below 2 cm. The production team used XGRIDS’ LCC Plugin for Unreal Engine to bring the model into the documentary.

The story so far

XGRIDS reconstructed 23.5 square kilometers of China’s Minning Town as a continuous 3D Gaussian model containing 6.2 billion Gaussian ellipsoids, which was featured in China Media Group’s documentary Minning Avenue. The project used 186,000 aerial and ground images and 15 billion LiDAR points collected over seven days. Leiphone reported that the reconstruction achieved centimeter-level geometric accuracy, with error below 2 cm. The documentary’s production team used XGRIDS’ spatial capture equipment, software and LCC data format for the reconstruction and visualization, then brought the model into Unreal Engine using XGRIDS’ LCC Plugin.
