Abstract
In the majority of conventional papers, the forward extraction of cars for ITS (intelligent transport systems) is intended for use in the daytime. However, if accident prevention is taken into consideration, measures to cope with nighttime, when more accidents occur, will become indispensable. Therefore, this paper considered forward vehicle extraction in the daytime and nighttime, respectively. In the daytime, since vehicles contain many horizontal surfaces, vehicle extraction was performed by taking surfaces greater than the threshold value as the width of the vehicle area, while at night, taillight extraction was performed using the Cr component of YCrCb color space. However, in light of recent research and advances in infrastructure, the research in this paper was conducted on the premise that exact lane tracking will be easily performable, and thus this issue was not considered. Comparatively good results were obtained on extraction of vehicles both in the daytime and at night. Future studies may be warranted to research the applicability of this technique in various environments.Keywords
