Object Classification in Natural Environments for Mobile Robot Navigation

摘要

The increasing interest in building autonomous mobile systems makes the detection and recognition of objects in natural environments is a very important and challenging task. In this paper, a vision system to detect objects considering natural environments, able to work on real mobile robot is developed. In the proposed system, the classification method used is Support Vector Machine (SVM) and as input to this system, RGB and depth images are used. Two approaches for implementing the selected classification method are explored, the prediction process one against all and one against one. The experimental results have demonstrated the usefulness of the system for detection and location of objects, and through the comparison of the two proposed approaches for the classification, has been determined which alternative offers better performance considering that the environment has not been changed, guaranteeing the naturalness of the place.
