在ROS中，使用`const std_msgs::String::ConstPtr&`作为回调函数参数，能够避免对象复制操作，提升性能效率。这里的`ConstPtr`实际上是`boost::shared_ptr`的别名。通过传递一个常量指针，我们确保了数据的直接引用，而非复制。具体而言，当消息被自动转换为C++代码时，会定义一些类型别名，如`Ptr`和`C...

在ROS中,sensor_msgs::PointCloud2ConstPtr广泛用于点云数据的传输和处理。由于点云数据通常包含大量的点,因此使用智能指针(如ConstPtr)可以高效地管理内存,同时保证数据在传输过程中的安全性和完整性。sensor_msgs::PointCloud2ConstPtr常用于以下场景: 传感器数据发布:传感器节点可以将采集到的点云数据封装为sensor_ms...
