Abstract

This study is an attempt to actualize the autonomous movement of a robot using a navigation system with a camera, instead of expensive external sensors such as light detection and ranging. The present implementation of our approach basically consists of road-following, intersection detection, and intersection recognition, using the results of semantic segmentation. In this study, we focus on the accuracy improvement of the intersection detection and recognition. Classifiers are constructed for these tasks using deep neural networks. We evaluated the proposed classifier using three-dimensional computer graphics generated from the CARLA simulator and the Ikuta dataset composed of actual images that we took. The Experimental results demonstrated that the proposed system could detect and recognize intersections accurately; the F measure exceeded 0.96 for detection, and the actual images were recognized and classified with perfect accuracy.
