Abstract:Road users make vital decisions to safely maneuver their vehicles based on the road markers, which need to be correctly classified. The road markers classification is significantly important especially for the autonomous car technology. The current problems of extensive processing time and relatively lower average accuracy when classifying up to five types of road markers are addressed in this paper. Two novel real time video processing methods are proposed by extracting two formulated features namely the cont… Show more
“…Based on the five common types of lane markers on the road [12][13][14], the number of contour lines ranges from zero to four. For example, the number of contour lines for marker S is two and D is four.…”

“…These are the most common types of lane markers and the easiest ones to be classified. A few lane marker classification schemes have been proposed in literature to detect the more challenging types of lane markers, which are DS and SD such as in [12,47,50]. Due to the difficulty in detecting and differentiating DS and SD, the accuracy of classifying these lane markers is typically lower than 90%.…”

“…Due to the difficulty in detecting and differentiating DS and SD, the accuracy of classifying these lane markers is typically lower than 90%. Our previous method in detecting five lane markers including DS and SD have been demonstrated to increase the accuracy between 94% to 100% [12], [14] in normal weather. With effective pre-processing techniques, this method can be further improved to be applied in foggy and rainy weather.…”

Driving vehicles in all-weather conditions is challenging as the lane markers tend to be unclear to the drivers for detecting the lanes. Moreover, the vehicles will move slower hence increasing the road traffic congestion which causes difficulties in detecting the lane markers especially for advanced driving assistance systems (ADAS). Therefore, this paper conducts a thorough review on vision-based lane marking detection algorithms developed for all-weather conditions. The review methodology consists of two major areas, which are a review on the general system models employed in the lane marking detection algorithms and a review on the types of weather conditions considered for the algorithms. Throughout the review process, it is observed that the lane marking detection algorithms in literature have mostly considered weather conditions such as fog, rain, haze and snow. A new contour-angle method has also been proposed for lane marker detection. Most of the research work focus on lane detection, but the classification of the types of lane markers remains a significant research gap that is worth to be addressed for ADAS and intelligent transport systems.

Road markers guide the driver while driving on the road to control the traffic for the safety of the road users. With the booming autonomous car technology, the road markers classification is important in its vision segment to navigate the autonomous car. A new method is proposed in this paper to classify five types of road markers namely dashed, single, double, solid-dashed and dashed-solid which are commonly found on the two lane single carriageway. The classification is using unique feature acquired from the binary image by scanning on each of the images to calculate the frequency of binary transition. Another feature which is the slopes between the two centroids which allow the proposed method, to perform the classification within the same video frame period. This proposed method has been observed to achieve an accuracy value of at least 93%, which is higher than the accuracy value achieved by the existing methods.
