1. The Precision SLAM Pipeline
How NavVis fuses LiDAR, IMU, and Vision into a survey-grade trajectory.
Multi-Sensor Fusion
Dual Hesai XT32 + IMU + 4x 20MP Cameras
Real-time 6-DoF SLAM
Dynamic tracking with local loop closures
Global Optimization
Bundle adjustment & control point snapping
Multi-Sensor Fusion
The VLX captures 1.28M points/sec via two perpendicularly mounted LiDAR sensors. This arrangement ensures 360° coverage of both horizontal structures (walls) and vertical features (floors/ceilings), critical for robust Z-axis tracking.
2. Data Workload Analysis
NavVis VLX produces structured **E57** or **LAS** point clouds. While traditional Terrestrial Laser Scanners (TLS) provide higher raw density at a single spot, the VLX's **Precision SLAM** ensures "thinner" slices and lower noise in the final unified cloud by optimizing the entire trajectory.
