代码说明:

单点定位也叫绝对定位是利用伪噪声码进行定位的主要形式,具有高效率、低成本等优点。理论上,只需要三颗卫星的观测值就可以求得测站三维坐标。考虑到接收机钟差影响,在定位时必须将接收机钟差当作一个未知参数与位置参数一起求解。因此,一般需要利用四颗以上卫星的伪距观测值才能进行定位。传统单点定位是指利用单台接收机的测码伪距及广播星历的卫星轨道参数和卫星钟差改正进行定位。由于测码伪距的精度一般为米级,广播星历的轨道精度为米级,卫星钟差改正精度为士纳秒左右,因此,关闭后,单点定位置信水平的平面精度是米级,高程精度是十米级。

  • Pack-Kurtogram
    快速计算一维信号的塔式谱峭度图,选择谱峭度最大值区间,方便确定所需滤波器中心频率及带宽。(Computes the fast kurtogram of signal x.This fast algorithm uses a pyramidal decomposition of the signal into a user-specified number of levels (a good choice is nlevel = 8). The first level is the classical kurtosis of the signal, the second level is the spectral kurtosis in 2 octaves, the third level the spectral kurtosis in 4 half-octaves, etc. Non-integer levels refer to divisions into third octaves. Here below is an illustration on how the frequency band is successively split when increasing the level)

  • MATLAB人体行为异常识别
    说明:  本文设计了一款人体行为异常监控系统,主要适用人群是老年人,在摄像头固定的情况下,自动检测人体运动轨迹,并与提前设定好的行为库进行匹配,分析判断是否具有异常行为。 在数字图像预处理部分采用了图像二值化,腐蚀与膨胀等几种方法为人体目标的跟踪和检测做准备。为了克服在实际操作中遇到的问题,采用了帧差法和ViBe算法,帧差法即利用帧间变化与当前帧、背景算法来判断它是否大于阈值,并分析视频中序列的运动特性,ViBe算法则是一种背景建模的方法,背景模型是由邻域像素来创建,并对比背景模型、当前输入像素值检测出前景,确定视频中的目标跟踪。在人体行为识别中,运动目标最小长宽比以及连续帧间的加速度来判断人体行为是否异常,如果检测到异常的行为比如说摔倒、快跑等行为,在识别的过程这种实时监测。不同环境可能需要调试,要求有一定编程基础,小白慎入。(In this paper, a monitoring system for abnormal human behavior is designed, which is mainly applicable to the elderly. When the camera is fixed, it can automatically detect the human motion track and match with the behavior database set in advance to analyze and judge whether there is abnormal behavior.)
