Hello

I work on Robotic Semantic Slam project. I have used octomap to build a global map incrementally. 

However, my project requires the construction of a local area map, which means that as the robot moves, the maps that have been constructed in the rear are continuously removed, and only the maps within a certain range of the current field of view are retained.

like this:

My project is approaching the deadline. Hope to get some methods. Thank you very much! 

Best regards
