Omnidirectional Vision Simulation and Robot Localisation

چکیده

Most work that is carried out for omnidirectional robot vision is done on real hardware, with expensive mirrors. In this paper a robot simulator with accurate omnidirectional vision capability is presented. Vertically aligned co-axial omnistereo vision with two conical mirrors (Spacek, 2005) is tested using the simulator. Experiments are performed to calculate the distance to six objects and the results are compared to the known distances. The calculated distances are then used in a simple natural landmark based localisation algorithm, and the estimated position of the robot is compared to the actual position.

Monocular Omnidirectional Vision based Robot Localisation and Mapping

Robot localisation is an important task in mobile robotics. In this paper a 2D simultaneous localisation and mapping implementation that uses only monocular omnidirectional vision is presented. Experiments are performed using a novel hybrid-simulation method to evaluate the SLAM algorithm based on the sensor model and the layout of the environment. Tests are then carried out that show the advan...

Navigation of a non-holonomic mobile robot with a memory of omnidirectional images

This paper extends our vision based navigation framework proposed in [2] to the entire class of central cameras (conventional and catadioptric cameras). During an off-line learning step, the robot performs paths which are sampled and stored as a set of ordered key images acquired by an embedded camera. The robot is then controlled by a vision-based control law along a visual route which joins t...

Path Following and Velocity Optimizing for an Omnidirectional Mobile Robot

In this paper, the path following controller of an omnidirectional mobile robot (OMR) has been extended in such a way that the forward velocity has been optimized and the actuator velocity constraints have been taken into account. Both have been attained through the proposed model predictive control (MPC) framework. The forward velocity has been included into the objective function, while the a...

Distributed Vision System for Robot Localisation in Indoor Environment

Traditional image-based localisation methods do not work when the robot is moving in an environment whose appearance is changing in time. We propose an extension to the classical image-based localisation that uses a Distributed Vision System (DVS) and can work also in highly dynamic environments. The DVS is composed of omnidirectional cameras installed in the environment and can communicate wit...
