Large-Scale Outdoor Scene Reconstruction
Reconstructed extensive outdoor environments using SfM/MVS pipelines for digital twin applications.
Overview
Developed and deployed a comprehensive pipeline for reconstructing large-scale outdoor environments including terrains, factories, and industrial sites. The system enables the creation of high-fidelity digital twins for simulation and industrial use cases.
Challenge
Large outdoor scenes present unique challenges including varying lighting conditions, scale consistency across vast areas, and computational efficiency for processing thousands of images.
Solution
Implemented an optimized SfM/MVS pipeline using COLMAP with custom camera calibration routines and distributed point cloud densification. Developed intelligent image selection algorithms to reduce redundancy while maintaining coverage.
Impact
Successfully delivered digital twins of multiple industrial facilities, enabling virtual inspection, planning, and simulation capabilities. Reduced on-site survey time while improving accuracy.
Key Highlights
- Optimized camera calibration and point cloud densification
- High-accuracy results at scale for digital twin applications
- Processing pipeline handles 10,000+ images efficiently
