US 10,255,508 B2 · Image evaluation method and electronic apparatus thereof to evaluate whether the vehicle is deviated from a lane

Abstract

An image evaluation method and an electronic apparatus thereof are provided. The method is adapted to the electronic apparatus installed at a vehicle for evaluating whether the vehicle is deviated from a lane, and the electronic apparatus includes at least one image capture unit. The method includes the following steps. An image related to driving environment is obtained by the image capture unit. According to an evaluation criterion, a plurality of candidate pair and corresponding candidate points in the image are evaluated from an arbitrary row of pixels of the image to recognize lane stripes in the image. A corresponding position of a feature portion of the vehicle corresponding to the image is calculated. The corresponding position of the feature portion corresponding to the image is compared with the lane stripes to determine whether the vehicle is towards or crosses over real lane stripes.
