Indoor dense depth map at drone hovering [article]

Autonomous flight in indoor requires a dense depth map for navigable space detection which is the fundamental component for autonomous navigation.  ...  The method also combines a plane sweep technique for image segments having almost no sparse point for initialization.  ...  Plane sweep runs a virtual plane perpendicular to the viewing direction from maximum to minimum depths obtained from sparse point cloud.  ...

In this work, we propose the use of a modified image mosaicing algorithm that coupled with image-based real-time navigation and mapping algorithms provides two visual navigation aids.  ...  applications, divers or pilots of remotely operated vehicles (ROVs) are still considered irreplaceable, and tools for real-time visualization of the mapped scene are essential to support and maximize the navigation  ...  The frame rate is also function of the operational distance, the camera field of view and vehicle speed.  ...
