DTW
DTW算法的程序,申请两个n*m的矩阵D、d,分别为累积距离和帧匹配距离。这里n和m为测试模版与参考模版的帧数。然后通过一个循环计算两个模版的帧匹配距离d。接下来进行动态规划,为每个格点 (i,j)都计算其三个可能的前续格点的累积距离D1,D2,D3。考虑到边界问题,有些前续格点可能不存在,因此加入一些判断条件最后利用最小值函数min(),找到三个前续格点的累积 距离作为累积距离,与当前帧的匹配距离d(i,j)相加,作为当前格点的累积距离。该计算过程一直达到格点(n,m),并将D(n,m)输出,作为模版匹配的结果。(DTW algorithm procedures, apply two n* m matrix D, d, respectively, accumulated distance and frame matching distance. Where n and m is a reference test pattern and the template frames. Then through a loop to calculate two frames template matching distance d. Next, dynamic programming, for each grid point (i, j) are calculated from the cumulative D1 before the renewal of its three possible lattice point, D2, D3. Taking into account the boundary problem, some former continued grid point may not exist, so add some conditions to determine the final use of the minimum function min (), found three former continued accumulation of grid points cumulative distance as the distance from the current frame to match the d (i, j) added, and a current cumulative distance grid. This calculation has reached the grid (n, m), and D (n, m) output, as a result of template matching.)

exp4
把激光陀螺捷联惯导系统和GNSS接收机固联于实验车实验仓中,接收机天线固联在实验车实验仓上方,车载计算机实时接收和采集惯导系统、卫星导航接收机的原始数据,在郊外开阔公路进行车载实验。
通过matlab编程实现卫星导航伪距单点定位、INS/GPS松组合导航的全过程。
1)卫星导航单点定位测速:利用采集得到的接收机时间、伪距、多普勒频移数据,要求进行单点定位、测速解算,输出接收机的位置、速度随时间的变化曲线,并给出位置、速度误差曲线;
2)松组合导航:结合惯导解算和卫星接收机单点定位测速,要求采用Kalman滤波器实现惯导/卫星位置、速度组合导航解算,滤波器维数至少包括惯导的位置、速度、姿态角9维。将组合导航后的姿态角与纯惯导的姿态角进行对比分析,给出位置、速度误差曲线。(The laser gyro strapdown inertial navigation system and GNSS receiver are fixed in the experimental compartment of the experimental vehicle. The antenna of the receiver is fixed above the experimental compartment of the experimental vehicle. The on-board computer receives and collects the original data of the inertial navigation system and satellite navigation receiver in real time, and carries out on-board experiments on the suburban open highway.)
