代码说明：

说明： PCL是一个类似于OpenCV的开源库，提供了很多三维点云的处理功能，其中就包括点云拼接。在三维扫描项目中，需要利用点云拼接方法将多次扫描得到的点云数据拼合成一个整体。在本例中，用一幅包含人脸的深度图像去匹配之前获得的人脸模板，这将使我们能够确定人脸在场景中的位置和方向。(PCL is an open source library similar to OpenCV, which provides a lot of processing functions for three-dimensional point clouds, including point cloud mosaic. In the three-dimensional scanning project, it is necessary to use point cloud mosaic method to combine the point cloud data obtained from multiple scans into a whole. In this example, a depth image containing face is used to match the face template obtained before, which will enable us to determine the position and direction of the face in the scene.)

电压跌落是最严重的动态电能质量问题之一，精确定位电压跌落起止时间是应对电压跌落问题的重要前提和基础。由于电压采样信号往往有噪声分量，现有的方法在定位电压跌落的起止时间时存在局限性。本文提出利用多小波变换及相邻系数去噪的电压跌落定位方法。多小波兼有对称性、正交性、有限支撑性和二阶消失矩等优异的信号处理性能，利用GHM多小波可以准确定位电压跌落起止时间。多小波变换系数在每层之间具有对应关系，多小波相邻系数将紧相邻的若干个系数作为一个整体来确定阈值，考虑了系数之间的相关性，能获得更好的去噪效果。通过 Matlab 进行仿真验证，仿真结果表明，所提出的方法的正确性。 (Voltage sag is one of the most serious dynamic power quality problems. Critical start-time and end-time are important indices for voltage sags. But the sampling signals often have noisy component, the locations of start-time and end-time are hard to get. Wavelet is an effective tool for those non-stationary signal processing and has been used in this field. Local feature in the signal can be enlarged after the transformation using the scalar wavelet. But scalar wavelets cannot contain orthogonality, symmetry, compact support and higher order of vanishing moments simultaneously. In this thesis, multi-wavelets GHM is used to detect and locate power quality disturbances. Multi-wavelets offer many excellent properties such as the same approximation order but more compact support. The dependence of the multi-wavelets coefficients varies with the level, so neighboring coefficien)
