usually not available in confined spaces and would not provide
sufficiently accurate estimates in cluttered environments.
Processors of MAVs have only limited processing power. It is intended to further reduce the size of MAVs to that of an
insect, hence necessitating lightweight and scalable position
estimation algorithms.
If sufficient computational and physical power is available, a typical
approach to estimate a UAV's position is by using active laser
rangefinders~\cite{grzonka2009towards,bachrach2009autonomous}.
...
However, this reduced physical payload is not without cost: it must be
traded off against the higher computational payload for the onboard
CPU.
Processors of MAVs have only limited processing power.
For example, a standard technique for 3D pose estimation extracts
keypoints of the current camera image and a map image and then
determines a homography between both keypoint sets. While this
approach has been used for visual SLAM for
