Toshiba Achieves Industry-First 99.9% LiDAR Tracking Accuracy


    1. Toshiba has developed the world’s first LiDAR sensor with 99.9% tracking accuracy.
    2. The LiDAR can precisely recognize objects and maintain high tracking stability even in low visibility conditions.
    3. The highly accurate LiDAR can enable autonomous driving capabilities and generate spatial digital twins.
    4. It represents a major advancement in object detection and tracking technology.
    5. The LiDAR sensor has applications in autonomous driving, infrastructure monitoring, and urban planning.
    6. Toshiba’s new LiDAR sets a new benchmark for precision and performance in 3D laser scanning technology.

Toshiba has announced revolutionary new LiDAR technologies that achieve unprecedented 99.9% accuracy in object tracking and 98.9% accuracy in object recognition using only LiDAR data.

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.
