Detailed Visual Recognition of Road Scenes for Guiding Autonomous Vehicles

Chapter

Abstract

Considerate re-use of elements of the Sobel-gradient operator also for corner detection in a new scheme allows unified extraction of edge-, corner- and linearly shaded blob features that can be done in real time taking recent microprocessor technology (GPUs) into account. In turn, this allows much more detailed visual recognition of complex road scenes in connection with corresponding knowledge bases on motion processes for dynamic vision. These subjects are discussed in a survey fashion as background material. The article concentrates on the new corner detection scheme looking directly for curvature components of the intensity function in several pairs of orthogonal directions. Typical results are shown for traffic scenes on highways. The new scheme is especially suited for recognizing blinking spot lights and brake (stop) lights.
