ptCloud = pointCloud(mat); I need the pointCloud becouse I'm working with pcregistericp. But now I need to plot this data, so I was thinking plot it with pcshow, but I would need to asign transparency inversely proportional to the number of points in each coordinates. ...

cloudPlot will help visualize the distribution of a 2-dimensional dataset. It is especially helpful when looking at extremely large datasets where a redular plot(x,y,'.') will just fill the plot with a solid color because the measurement points overlap each other. ...
点云可用由机器人领域的多种传感器采集,如LIDARS、Kinect和立体摄像机。ROS中最常用的传输点云的消息类型是“sensor_msgs/PointCloud2”,MATLAB提供了一些专业的函数供用户使用点云数据。小车上未装备有深度相机,暂时拿不到pointcloud2: 读取点云位置: xyz = readXYZ(ptcloud) ...
