hi，I followed your steps to update the code in pointcloudmapping.cc, but I compiled it with error. What should I do to fix this problem? Thank you for your time!

试试滑动鼠标滚轮缩小一下，我开始也只看到坐标系，后来发现是局部点云被放得太大了而看不出整体的点云结果

在viewer函数里把showCloud函数提前，可以解决这个问题。具体见https://blog.csdn.net/Xuesengxinyi/article/details/93469079
