资源说明:In this paper, we present a novel sensor-fusion method that reconstructs trajectory of mobile devices from MEMS inertial measurement unit (IMU). In trajectory reconstruction, the position estimation suffers seriously from the errors in the raw MEMS data, e.g. accelerometer signal, especially after its second-order integration over time. To eliminate the influence of the errors, a new error model is proposed for MEMS devices. The error model consists of two components, i.e. noise and bias, corres
