Abstract本申请涉及一种轨迹重建方法、装置、计算机设备和存储介质。所述方法包括:采集终端设备在多个时间点的惯性传感器数据及无线保真网络的信号强度数据;根据各时间点的无线保真网络的信号强度数据,生成各时间点的初始定位坐标;根据各时间点的惯性传感器数据,生成各时间点的位移向量;将各时间点对应的初始定位坐标及位移向量输入全局定位模型,得到各时间点的最终定位坐标;根据各最终定位坐标进行轨迹重建。采用本方法能够在复杂的物体运动模式以及无线传播环境下得到更加准确的位置估计,提升了轨迹重建的精度。
Other AbstractThe present application relates to a trajectory reconstruction method and apparatus, a computer device and a storage medium. The method comprises : acquiring inertial sensor data of a terminal device at a plurality of time points and signal strength data of a wireless fidelity network; generating, according to the signal strength data of the wireless fidelity network at each time point, initial positioning coordinates corresponding to each time point; generating, according to the inertial sensor data at each time point, a displacement vector corresponding to each time point; inputting the initial positioning coordinates and displacement vectors corresponding to the time points into a global positioning model, so as to obtain final positioning coordinates of the time points; and performing trajectory reconstruction according to the final positioning coordinates. By means of the method, a more accurate position estimation can be obtained in a complex object motion mode and a wireless propagation environment, thereby improving the accuracy of trajectory reconstruction.
