Hi @montecarlo13
In that case you can either use Elevation Mapping or add the point clouds to a grid map in your own node, both ways will work.
Does that answer your question?

Hi @pfankhauser
Thank you very much for your answer. Now I have a idea, I would firstly use OpenCV to process my depth images, which published by the sensor, then in my node I use the classes GridMapCvConverter and GridMapCvProcessing from the grid map library for converting the cv messages to /grid_map_msgs/GridMap, so that I can get the OccupancyGrid map with help from the node grid_map_visualization. Will that work? Thanks!

I don't think you need OpenCV for this. Just take your depth images, turn them into point clouds and either use Elevation Mapping or your own implementation to add the point clouds to a grid map. Does this help?
