Application of EKF in Laser/Inertial Sensors Localization System

To realize the precise localization of the field working machine, the localization system which based on Laser/ Inertial Sensors (Laser/INS) was designed. Meanwhile, the system model was established, the Extended Kalman Filtering (EKF) algorithm was proposed, and the simulation was accomplished by Matlab. The simulation results show that the location system using the filter algorithm can keep precise estimation in long time, and can locate the field working machine real-timely.
