Analysis of Map Information in Dynamic Environment

When the robot moves in the room, it's essential to build a map to guide it. Currently, there is a method to establish the maps in real time called simultaneous localization and mapping. Due to the complexity of the surrounding environment and the influence of the accuracy of sensors on the construction of the map, the correctness of mapping will be greatly affected. This article is based on previous research. This operation uses the algorithm based on robot operating system. We design the algorithms to identify changings between the maps of indoor states and achieve good results.
