Kudan GrandSLAM

Localization and mapping/ SLAM with all sensors for maximum performance

  • Accepts a wide range of sensor data such as camera, ToF, Lidar, IMU, GNSS, and wheel odometry. A camera or Lidar can currently be used as the primary sensor.
  • Provides commercial grade performance: High accuracy, low processing time, maximum robustness, huge map scalability, robust system stability, low integration complexity, cross-platform portability.
  • Unlocks the full potential of your system with significant performance gains against alternative approaches.

Sensor configuration freedom and incomparable performance on your hardware

  • Ultimate flexibility of sensor requirements and configuration, no need to use expensive or complex sensors.
  • Solution to the most critical multi-sensor system pain point, our technology can enable synchronization and calibration between all sensors.

Visual SLAM

Commercial grade, faster processing, lower memory, higher accuracy, and greater robustness

Lidar SLAM

Overcome typical Lidar localization and mapping problems with higher accuracy, reduced map size, and lower latency

  • Leverages our deep expertise in visual SLAM to reach groundbreaking performance, including 1cm-level accuracy, and greater than 300x lighter map size over raw Lidar data.
  • Almost zero pose estimation latency when combining with an IMU.
  • Compatible with many different types of Lidar technology such as, spinning, solid state, and prizm based.
  • Ability to correct motion blur in the Lidar data stream while mapping resulting in sharper point clouds and improved post AI process such as object recognition
  • Reference dataset is available here
    (Dataset – a dataset targeting autonomous driving, outdoor robotics: coming soon)


Artisense’s GN-net relocalization: AI-enabled (re)localization that is incredibly robust to scenery changes

  • Overcomes the challenge of how to localize a vehicle or machine when the scenery or conditions change over time.
  • Uses “deep-features” identified by AI for matching correct locations even when their appearance is different.
  • Map can be updated automatically to include any changes that are detected.

Tight coupling and Time synchronization

Integrate all the sensor information into one system rather than just “filtering” them with accurate time synchronization

  • Common sensor fusion approach is a “loose-coupling” of sensors, while Kudan and Artisense use “tight-coupling”.
  • The Kudan group has developed the only system that uses tight-coupling of all sensors including camera, Lidar, GNSS and IMU.
  • Problematic issues of proper time synchronization are solved with micro-second level synchronization between all sensors.
  • Unparalleled robustness and accuracy for a wide range of use cases.

Extrinsic calibration and motion blur correction

Enabling LiDAR OEMs and users to achieve better extrinsic calibrations and correct motion blur using our extensive computer vision capability leading to more accurate maps and improved recognition performance

  • Lack of accurate extrinsic calibrations and motion blur cause highly visible degradation to LiDAR point clouds in all applicable use cases.
  • Accurate localization and understanding of vehicle / machine ego-motion can provide better extrinsic calibrations between sensors and sharper point cloud maps even with high-speed movement or fast rotation.
  • Applicable to more than just SLAM, the improved calibration and point clouds are also applicable to image recognition, resulting in increased safety and system reliability.

Map handling

Practical functionality for large scale map management

  • Simple to use map handling such as loading, merging, splitting, saving, and unloading.
  • Multiple maps can be loaded to cover the same area, allowing unmatched performance against changing scenery.
  • Maps can be loaded and unloaded into Kudan software while running allowing for unlimited scale maps.

Processor and sensor optimization

Unprecedented speed and other performance gains at low power through processor and sensor optimization

  • Kudan has been proactively working with sensor and processor players to optimize KudanSLAM algorithms.
  • Provides unparalleled speed, robustness, accuracy and power consumption when combined with specific processors / sensors.
