Abstract
This work investigates the research topics related to visual aerial navigation in loosely structured and cluttered environments. During the inspection of the desired infrastructure the robot is required to fly in an environment which is uncertain and only partially structured because, usually, no reliable layouts and drawings of the surroundings are available.
To support these features, advanced cognitive capabilities are required, and
in particular the role played by vision is of paramount importance. The use
of vision and other onboard sensors such as IMU and GPS play a fundamental to
provide high level degree of autonomy to flying vehicles. In detail, the outline of
this thesis is organized as follows
• Chapter 1 is a general introduction of the aerial robotic field, the quadrotor
platform, the use of onboard sensors like cameras and IMU for autonomous
navigation. A discussion about camera modeling, current state of art on vision
based control, navigation, environment reconstruction and sensor fusion
is presented.
• Chapter 2 presents vision based control algorithms useful for reactive control
like collision avoidance, perching and grasping tasks. Two main contributions
are presented based on relative depth map and image based visual
servoing respectively.
• Chapter 3 discusses the use of vision algorithms for localization and mapping.
Compared to the previous chapter, the vision algorithm is more complex
involving vehicle’s poses estimation and environment reconstruction. An algorithm
based on RGB-D sensors for localization, extendable to localization
of multiple vehicles, is presented. Moreover, an environment representation
for planning purposes, applied to industrial environments, is introduced.
• Chapter 4 introduces the possibility to combine vision measurements and
IMU to estimate the motion of the vehicle. A new contribution based on Pareto Optimization, which overcome classical Kalman filtering techniques,
is presented.
• Chapter 5 contains conclusion, remarks and proposals for possible developments.
