Zerolag tracking is a key feature of Kudan's GrandSLAM technology. This article introduces a summary of the feature.<\/p>\n

 <\/p>\n

<\/h3>\n

What is Zerolag tracking<\/strong><\/h3>\n
    \n
  • \n

    - Generally, automotive-grade LiDARs work at 5 to 20Hz. For automotive use cases, sensors can travel 1 to 5m over each scanning<\/p>\n<\/li>\n

  • \n

    - This 1 to 5m can cause many issues, especially in some cases which require highly accurate localisation and mapping<\/p>\n<\/li>\n

  • \n

    - Using Kudan\u2019s GrandSLAM, the system can correct and update the position of the sensor with the frequency of fused IMU which can generally run-up to the order of tens kHz, and compress the latency of position recognition less than ten micro sec<\/p>\n<\/li>\n

  • \n

    - This enables system output with practically zero lag for vehicle localisation and minimizes the real-time tracking accuracy into less than several cms<\/p>\n<\/li>\n<\/ul>\n

    Benefits of Zerolag tracking<\/strong><\/h3>\n
      \n
    • \n

      - Vehicle\/ robot localisation can work even the sensors move with high speed and quick turns. This can contribute to highly accurate and real-time localisation for automotive, drones, aircrafts<\/p>\n<\/li>\n

    • \n

      - The algorithm can save processing consumption with keeping the output frequency and latency, which enables the algorithms working on lower graded processors and\/ or providing more processing power for other algorithms (e.g., object recognition, navigation)<\/p>\n<\/li>\n<\/ul>\n

      <\/h3>\n

       <\/p>\n

      Example of Zerolag tracking<\/strong><\/h3>\n
        \n
      • \n

        - We have run GrandSLAM on general automotive-grade LiDAR data and compared the results with and without IMU synchronisation<\/p>\n<\/li>\n

      • \n

        - The result without IMU showed a latency of 50 to 60 milliseconds, while the result with IMU showed a latency of less than 10 microseconds, confirming that it is possible to output a position 5000 times faster and it's almost ignorable for any practical use cases<\/p>\n<\/li>\n<\/ul>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/article>\n<\/div>\n
