Abstract
A road region detection method is provided. The method includes: obtaining a first image captured by a camera at a first time point and a second image captured by the camera at a second time point (S), converting the first and second images into a first top view and a second top view, respectively (S), obtaining a movement vector matrix which substantially represents movement of a road region relative to the camera between the first and second time points (S), and determining whether a candidate point belongs to the road region by determining whether a position change of the candidate point between the first and second top views conforms to the movement vector matrix. The accuracy and efficiency may be improved.
