TY - JOUR PY - 2018// TI - Road scene simulation based on vehicle sensors: an intelligent framework using random walk detection and scene stage reconstruction JO - Sensors (Basel) A1 - Li, Yaochen A1 - Cui, Zhichao A1 - Liu, Yuehu A1 - Zhu, Jihua A1 - Zhao, Danchen A1 - Yuan, Jian SP - s18113782 EP - s18113782 VL - 18 IS - 11 N2 - Road scene model construction is an important aspect of intelligent transportation system research. This paper proposes an intelligent framework that can automatically construct road scene models from image sequences. The road and foreground regions are detected at superpixel level via a new kind of random walk algorithm. The seeds for different regions are initialized by trapezoids that are propagated from adjacent frames using optical flow information. The superpixel level region detection is implemented by the random walk algorithm, which is then refined by a fast two-cycle level set method. After this, scene stages can be specified according to a graph model of traffic elements. These then form the basis of 3D road scene models. Each technical component of the framework was evaluated and the results confirmed the effectiveness of the proposed approach.
