Electrical Bus Rapid Transit (eBRT) is a charging electrical public transport which
brings a clean, high performance, and affordable cost alternative from the conventional
traffic vehicles which work with combustion and hybrid technology. These buses charge the
battery in every bus stop to arrive at the next station.
But, this charging system needs an appropriate infrastructure called pantograph, and
it requires a high precision bus location to maintain battery lifetime, energy saving and
charging time. To overcome this issue Vicomtech and Datik has planned a project based
on computer vision to help to the driver to locate the vehicle in the correct place. In
this document, we present a mono camera bus driver guided fast algorithm because these
vehicles embedded computers do not support high computation and precision operations.
In addition to the frequent lane sign, there are more accurate geometric beacons painted on
the road to bring metric information to the vision system. This method uses segmentation
to binarize the image discriminating the background space. Besides it detects, tracks and
counts different lane mark contours in addition to classify each special painted mark. Besides it does not need any calibration task to calculate longitudinal and cross distances because we know the lane mark sizes.
