点云数据通常以xyz坐标形式表示,我们可以使用MATLAB提供的PointCloud对象或者其他格式如PLY、OBJ等来存储点云数据。 2.数据预处理 为了提高点云分割算法的效果,我们可以进行数据预处理。例如,我们可以对点云进行滤波操作,去除噪声点;或者对数据进行降采样,减少数据量。MATLAB提供了各种滤波和降采样的函数,如pcdenoise和...
A point cloud is a collection of data points in 3D space, where each point represents the X-, Y-, and Z-coordinates of a location on a real-world object’s surface, and the points collectively map the entire surface. Point clouds are commonly produced bylidar scanners, stereo cameras, a...
