1. On-line SLAM using clustered landmarks with omnidirectional vision
The problem of SLAM (simultaneous localization and mapping) is a fundamental problem in autonomous robotics. It arises when a robot must create a map of the regions it has navigated while localizing itself on it, using results from one step to increase precision in another by eliminating errors inherent to the sensors. One common solution consists of establi

2. Avaliação de um método baseado em máquinas de suporte vetorial de múltiplos núcleos e retificação de imagens para classificação de objetos em imagens onidirecionais. / Assessment of a method based on multiple kernel support vector machines and images unwrapping for the classification of objects in omnidirectional images.
Apesar da popularidade das câmeras onidirecionais aplicadas à robótica móvel e da importância do reconhecimento de objetos no universo mais amplo da robótica e da visão computacional, é difícil encontrar trabalhos que relacionem ambos na literatura especializada. Este trabalho visa avaliar um método para classificação de objetos em imagens onidir

3. Localização e mapeamento simultâneos com auxílio visual omnidirecional. / Simultaneous localization and mapping with omnidirectional vision.
The problem of simultaneous localization and mapping, known as the problem of SLAM, is one of the greatest obstacles that the field of autonomous robotics faces nowadays. This problem is related to a robots ability to navigate through an unknown environment, constructing a map of the regions it has already visited at the same time as localizing itself on thi

4. Auto-localização e construção de mapas de ambiente para robôs móveis baseados em visão omnidirecional estéreo. / Simultaneous localization and map building for mobile robots with omnidirectional estereo vision.
This project aims the development of a system for self localization and environment map building for mobile robots in a structured environment. The map is built from images acquired by an omnidirectional stereo system with a hyperbolic double lobed mirror. From a single acquired image, using stereo vision algorithms, the environment around the robot is tridi

5. Development of an omnidirectional vision system
Omnidirectional vision systems can provide images with a 360° of field of view. For this reason, they can be useful to robotic applications such as navigation, teleoperation and visual servoing. An effective way to construct this type of vision system is by combining lenses and mirrors together resulting on a system that does not require the movement of the

6. Evidence grids with omnidirectional stereovision for mobile robots. / Grades de evidência com visão estéreo omnidirecional para robôs móveis.
Autonomous mobile robots depend on information acquired with its sensors to make decisions during its task. The use of vision systems provide a large amount of data about the environment in which the robot is. Particularly, an omnidirectional vision systems provide information in all directions of the environment to the robot with just one image. Through the

7. Map building for mobile robot navigation with omnidirectional stereo vision. / Construção de mapas de ambiente para navegação de robôs móveis com visão omnidirecional estéreo.
O problema de navegação de robôs móveis tem sido estudado ao longo de vários anos, com o objetivo de se construir um robô com elevado grau de autonomia. O aumento da autonomia de um robô móvel está relacionado com a capacidade de aquisição de informações e com a automatização de tarefas, tal como a construção de mapas de ambiente. Sistemas d
