Description

Hi, I am sorry to bother you again.

Now I can add distance field and publish it successfully. But I face some new problems:
![e1](https://user-images.githubusercontent.com/49118957/136252977-6576df0a-a69d-42a7-af16-d15b9d11bf24.png)

I try to change **ros::Duration()** but it didn't fix the problem.
After searching similar issues at community, I run this command:
**rosrun tf static_transform_publisher 0 0 0 0 0 0 world velodyne 10**
![e2](https://user-images.githubusercontent.com/49118957/136254452-41482bdf-9b1d-4919-8bb8-33d0d2acbd55.png)
It seems that fix the transform error but still have the "process has died" problem.

Additionally, I can see the "Segmented Cloud" only at first frame.

May i have your suggestions to fix this problem?
Any help is much appreciated:)
