LiDAR (Light Detection and Ranging) uses lasers to measure distances and construct detailed 3D maps of environments. Toshiba’s breakthroughs will significantly advance spatial digital twins – virtual replicas of real-world spaces like factories and cities.

Previously, spatial digital twins were limited because LiDAR suffered in bad weather without cameras. Toshiba overcame this with three innovations:

1. 2D/3D Fusion AI
   • Combines 2D luminance data and 3D point cloud data from the LIDAR sensor
   • Applies AI for highly accurate object recognition (98.9%) and tracking (99.9%)
   • Eliminates issues with camera-LIDAR misalignment and vibration
   • Enables precise perception using LIDAR alone, without needing a camera
2. Rain/Fog Removal Algorithm
   • Removes noise and interference from rain and fog that degrades LIDAR performance
   • Analyzes waveform characteristics to identify rain/fog reflections
   • Doubles detection range in heavy rain and fog conditions
   • Improved detection: 20m to 40m in heavy rain, 17m to 35m in fog with 40m visibility.
3. Variable Measurement Range
   • Toshiba’s new LiDAR tech enhances performance with smaller projectors.
   • Range increased by 1.5 times while meeting safety standards.
   • Changes in projectors and lens boosted range and widened the viewing angle sixfold.
   • Testing achieved 120m range with specific viewing angles.
   • Achieves up to 350m range, the longest in the world.
   • Promising for spatial digital twins and wide-angle applications.

These technologies enable robust and accurate LiDAR mapping in all conditions. By enhancing performance, Toshiba has enabled real-world deployment of spatial digital twins to optimize automated driving, smart factories, warehouses, and cities.

The breakthroughs represent a major advancement for LiDAR and its applications across industries. Toshiba is pioneering sensing innovations to drive digital transformation.
