Splet众所周知，C++的STL容器的内存大小会随着数据数量的增加而增长。 对于vector和string来说，每当须要更多的内存空间时（比如push_back操作），该容器就调用与realloc类似的操作。 而这个操作大概如下： 为当前容器分配一块新内存，内存大小为当前容量的某个倍数（通常为2倍）； 将该容器内的全部元素从旧的内存复制到刚才新分配的内存中。 析构掉旧 … Spletpcl库是一个强大的点云处理库，在c++中使用极其方便，而python版本中因为笔者没有安装python-pcl（也是为了追求多样性），代码看起来略显繁杂。 同时，c++版本中也展示了ros中sensor_msgs::PointCloud2格式与pcl中pcl::PointCloud、pcl::PointCloud的相互转换方法，请读者留意。 references blog.csdn.net/k_NGU_L/a 发布于 2024-10-14 18:26
