What should I do to make these areas that should be ground also marked light gray?

According to the above, when I set the parameter Grid / RayTracing to true and Grid / 3D to false, can rtabmap convert t

Timed out waiting for transform from base_footprint to rtabmap/odom to become available before running costmap I use rta

In other words, I need to write a node or package to subscribe to the color images and depth images of the depth camera,
