Research on Indoor Navigation System of UAV Based on LIDAR

In the indoor environment, the reinforced concrete structure in the building easily shields the indoor satellite signals, which makes it unable to provide effective real-time positioning information, which greatly limits the function implementation of the drone in special environments such as indoor. An indoor navigation system based on LIDAR is used to solve the problem of indoor structures blocking satellite signals. In this paper, LIDAR is used as a sensor to sense the environment. Synchronous positioning and mapping algorithms are used to provide effective real-time positioning information. The drone is separated from the dependence on satellite signals, and finally realizes the autonomous navigation and map construction of the drone in special environments such as indoors.
