Abstract

When autonomous mobile robots need to navigate by vision in indoor environments,
powerful direction-finding and steering clues are provided by the lines of perspective in the image.
These are neither vertical nor horizontal. In a real-time navigation task it is important to obtain this
information as efficiently as possible, and is the motivation for this research. The Roberts and Sobel
operators are amongst the most efficient and well known for locating edge segments which provide
the information required. In this paper the outputs of the Roberts operators are compared with that of
Sobel, and a subtle variant of the Roberts is introduced and compared with these.
