It should play a main role regarding UAVs' functionality because of the big amount of information that can be extracted, its possible uses and applications, and its natural connection to human driven tasks, taking into account that vision is our main interface to world understanding. Our current research's focus lays on the development of techniques that allow UAVs to maneuver in spaces using visual information as their main input source. This task involves the creation of techniques that allow an UAV to maneuver towards features of interest whenever a GPS signal is not reliable or sufficient, e.g. when signal dropouts occur (which usually happens in urban areas, when flying through terrestrial urban canyons or when operating on remote planetary bodies), or when tracking or inspecting visual targets -including moving ones-without knowing their exact UMT coordinates. This paper also investigates visual servoing control techniques that use velocity and position of suitable image features to compute the references for flight control. This paper aims to give a global view of the main aspects related to the research field of computer vision for UAVs, clustered in four main active research lines: visual servoing and control, stereo-based visual navigation, image processing algorithms for detection and tracking, and visual SLAM. Finally, the results of applying these techniques in several applications are presented and discussed: this study will encompass power line inspection, mobile target tracking, stereo distance estimation, mapping and positioning.

At the same time, the process of optimizing and fine-tuning mathematical models has been increasingly aided by the advent of high-performance computational environments. Analytical models are used to characterize and optimize their performance via closed-form solutions, numerical solutions, or, in some cases, solutions inferred through observation. Of course, the ability of a particular mathematical construct to reflect reality is dependent on what expression of reality one wants to model with it; nonetheless, computational experiments permit a higher degree of parametrization of physical phenomena without the expense or dangers of a flawed outcome. Robotics manipulators are highly complex systems; consequently, the development of computational platforms that allow for their precise modeling, and close to real-life simulation of their behavior, constitute a fundamental tool for robot designers, users, and students of the field. This reason has inspired the creation of numerous graphical software environments, from nonrobot-manufacturers, such as: RoboWorks (1], Robot Assist (2), Easy-ROB3D (3), WorkspaceS (4), and also from the manufacturers themselves.
