Description:
In the last years, unmanned aerial vehicle (UAV)
systems have become very attractive for various commercial,
industrial, public, scientific, and military operations.
Potential tasks include pipeline inspection, dam surveillance,
photogrammetric survey, infrastructure maintenance,
inspection of flooded areas, fire fighting, terrain monitoring,
volcano observations, and any utilization which
requires land recognition with cameras or other sensors.
The flying capabilities provided by UAVs require a welltrained
pilot to be fully and effectively exploited; moreover
the flight range of the piloted helicopter is limited to the
line-of-sight or the skill of the pilot to detect and follow the
orientation of the helicopter. Such issues are even more
important considering that the vehicle will carry and
operate automatically a camera used for a photogrammetric
survey. All this has motivated research and design for
autonomous guidance of the vehicle which could both
stabilize and guide the helicopter precisely along a
reference path. The constant growth of research programs
and the technological progress in the field of navigation
systems, as denoted by the production of more and more
performing global positioning systems integrated with
inertial navigation sensors, allowed a strong cost reduction
and payload miniaturization, making the design of low-cost UAV platforms more feasible and attractive. In this paper,
we present the results of a flight simulation system
developed for the setup of the vehicle’s servos, which our
autonomous guidance system, as well as the module for
camera photogrammetric image acquisition and synchronization,
will be based on. Building a simulated environment
allows to evaluate in advance what the main issues of a
complex control system are to avoid damage of fragile and
expensive instruments as the ones mounted on a model
helicopter and to test methods for synchronization of the
camera with flight parameters.
