Project Description

The primary goal of the project is the development of a mobile robot mounted active vision system capable of learning and recognizing objects in an industrial setting. The system should be able to learn its surroundings in a supervised form, as well as the more relevant objects that allow for the completion of a particular task.

By incorporating several perception sensors (computer vision, proximity sensors, acoustic sensors), the system should be capable of producing a map of the environment, in which the user can select, via a graphical user interface or via voice commands, the location of selected objects for learning and recognition.

The mobile robot would autonomously navigate to the selected object, and take snapshots of the object from different viewpoints, thus capturing invariant appearance and geometric object features, as well as acoustic signatures, for object characterization. Once a map of the environment has been created, and the relevant objects have been learned, the robot should be able to navigate through the environment identifying the learned objects; even if there have been significant changes in the environment from the learning phase to the recognition phase. This is, the system must be able to react to dynamic or changing environments by keeping at all times an updated version of a continuously learned environment map.

The system will be designed for a somewhat structured but changing environment in mind. This project is the continuation of a previous CICYT project assigned to the main investigator on 1998, in which we developed robust learning techniques for a mobile robot called MARCO using active vision.In this project we will develop robust techniques for the extraction and learning of invariant image features based on color, texture, and geometry.

Object representation will be enriched with the signatures coming from position and acoustic sensors. We will come up with the necessary techniques for the fusion of information from the various perception sensors. We will extend our group's contributions on state of the art object model representation techniques based on probabilistic graphs, particularly on function described graphs. We will further investigate algorithms for probabilistic graph synthesis and graph matching for the learning and recognition of object models, respectively. We will develop a dynamic and scale-invariant scene representation model (map) that will preserve relational information among the salient landmarks in the environment, and that allows for the annotation of context-based information by the user. In order to test our map building and recognition algorithms as well as our object model learning and recognition methods, we will develop the required reactive navigation behaviors for obstacle avoidance, as well as deliberate (map based) behaviors that allow for the planning of more complex navigation trajectories. We will also come up with efficient probabilistic local and global self-localization methods according to our environment representation model.
