c++ ros grid_map pcd

问题遇到的现象和发生背景

grid_map 下grid_map_pcl模块进行pcd点云的格式转换成带有高程信息的地图，转换完成但是不会显示出来，也只有一点警告，但是感觉不是正常的
运行命令也只有这一行

roslaunch grid_map_pcl grid_map_pcl_loader_node.launch 

遇到的现象和发生背景，请写出第一个错误信息

运行结果及详细报错内容

我的解答思路和尝试过的方法，不写自己思路的，回答率下降 60%

我使用一些内存大约1mb或者100kb的pcd点云信息就可以直接转换出高程信息，目前是200m到500m左右的，个人猜测不是和内存有关，这个pcd可能是由于las点云转换而来导致的错误？各位朋友有没有遇到的相类似的bug呢？
