The invention relates to a lane departure early warning method suitable for a mobile terminal, and the method comprises the steps: obtaining a lane scene image through the mobile terminal, and carrying out the dynamic region-of-interest division of the lane scene image; performing lane line feature enhancement on the image of the region of interest; performing far-field and near-field region segmentation and feature extraction on the lane line; performing straight line fitting on the near-field lane line, and performing curve fitting on the far-field lane line; and performing lane departure early warning according to the absolute value ratio of the near-field left and right lane line slopes. According to the method, through dynamic region-of-interest division, the information acquisition range can be adjusted, lane information can be accurately acquired, and redundant information can be removed. The deviation early warning operation is relatively simple, and lightweight mobile equipment can be loaded completely.
本发明涉及一种适用于移动终端的车道偏离预警方法，包括：通过移动终端获取车道场景图像，并对车道场景图像进行动态感兴趣区域划分；对感兴趣区域图像进行车道线特征增强；对车道线进行远、近场区域分割和特征提取；对近场车道线进行直线拟合，对远场车道线进行曲线拟合；根据近场左、右车道线斜率的绝对值比值进行车道偏离预警。本发明的方法通过动态感兴趣区域划分，可以调整信息获取的范围，精准的获取车道信息，去除冗余信息。偏离预警运算较为简单，轻量级的移动设备完全可以负荷。
