然后定义了用于将sensor_msgs.msg.PointCloud2类型消息对象读取到numpy数组的read_points()函数。该函数有四个输入参数:第一个参数cloud用于指定要读取的PointCloud2消息对象变量;第二个参数field_names用于指定要读取的字段名称,默认值为None;第三个参数skip_nans用于指定是否不返回即跳过具有NaN值

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, ...
