Research on Location Method Based on GNSS/IMU/LIDAR Multi-source Information Fusion

In recent years, unmanned mobile platforms have been applied more and more widely in various fields of society, and the market has a strong actual demand for consumer navigation and positioning system. In this paper, a localization algorithm based on GNSS/IMU integrated navigation system combined with Lidar odometer is proposed. Graph optimization is used for multisensor data fusion. Experiments show the excellent performance of the algorithm.
