      interface IPerceptionManager extends IVisualManager, IPerceptionCommon
      Package:dji.v5.manager.interfaces
      Inherits From:IVisualManager, IPerceptionCommon
      Description:

      This class is perception management class, which is used to turn on and turn off the obstacle avoidance switch, set the type of obstacle avoidance, set warning distance, braking distance and other functions. At the same time, you can call getRadarManager to get the information and data of the millimeter-wave radar accessories (if installed).
