State Estimation and Localization of an autonomous vehicle based on IMU (high rate), GNSS (GPS) and Lidar data with sensor fusion techniques using the Extended Kalman Filter (EKF). sensor-fusionekf-localization UpdatedJan 1, 2020 Python
IMU的航迹推演(dead-reckoning)随着时间的推移,误差不断累积,为了避免定位位置出现偏移,需要每隔一段时间,都需要将IMU信息与GPS测量信息或者视觉定位信息进行融合.ES-EKF就是融合这些多传感器信息的有效方法之一. 4.Error State Extended Kalman Filter的优势 1.The orientation error-state is minimal (i.e., it ha...

High accuracy and frequency local localization is the key technology of unmanned aerial vehicles (UAVs) in the confined areas and complicated conditions such as indoor flight, landing on ship deck and flight in GPS-denied environments and so on. In this paper, based on ultra-wideband (UWB) ...
However GPS signals contain unwanted information contaminated by environmental components and many interference signals. In this paper, to obtain TDoA signal, we use two UAVs which are equipped with embedded wireless sensors. Under the real geolocation circumstance, it is very difficult to estimate the...
