Get3D Mapper: Six Strategic Advantages for City-Scale 3D Reconstruction

Overview

Get3D Mapper is the core processing engine powering city-scale 3D reconstruction. Engineered specifically for large-scale urban projects, it delivers six strategic advantages:

1. Robust Aerial Triangulation

ADMM with Unified Measurement Unit is applied to solve the problem of Joint Aerial Triangulation for millions of images.

Aerial triangulation

  • Dynamic block partitioning, no need to merge blocks to solve the problem
  • Convergence speed and accuracy are better than ADMM method in CVPR2017
  • The accuracy is close to that of the overall AT solution (the error difference in the inverse projection is <1e-3 pixels)

2. Geometry & Texture Consistency

（1） Global and local balanced 3D model color adjustment

  • After Color Balancing: Colors are harmonized across the model, with smooth transitions and natural detail rendering for a more uniform and realistic appearance.

（2） Clean results with seamless block merging

  • Geometry Difference: Get3D Mapper analyzes and adjusts block geometry to minimize spatial inconsistencies, ensuring a unified, continuous mesh.
  • Texture Mosaic: Uses intelligent texture blending and color harmonization algorithms to generate a seamless texture mosaic across blocks.

（3） Illumination Problem

When images are taken at different times or under varying sunlight, Get3D Mapper fixes this with smart light adjustment, making the model look smooth and natural.

5. Parallel & Cluster Computing

Remote-Free Operation

  • No need for remote desktop access to each node
  • Directly manage and monitor all nodes through the central Engine
  • Reduces IT complexity and operational friction

Efficient Batch Management

  • Submit and manage multiple tasks across nodes
  • Queue optimization for large-scale or repetitive jobs
  • Streamlines high-volume processing workflows

Real-Time Monitoring

  • Task progress, system load, and resource usage are visible at a glance
  • Instant alerts on errors or delays
  • Enables proactive management and fast troubleshooting
