The invention discloses a lane keeping assisting method based on image recognition. High-definition cameras are installed in multiple directions of a vehicle and video data are transmitted to a database in real time; a video conversion module extracts instant pictures at certain intervals according to high-definition videos and stores the instant pictures in a picture format; a microprocessor extracts the instant pictures, compares the instant pictures according to a time sequence, compares the instant pictures according to a set comparison condition, and performs comprehensive evaluation specifically according to a driving speed and a change absolute value; and when lane departure is determined, the microprocessor calculates an adjustment scheme according to the departure direction and the driving speed and sends a command to a steering wheel electronic power-assisted system, and the steering wheel electronic power-assisted system adjusts the steering wheel according to the adjustmentcommand. According to the method, the lane is guaranteed to be normal, discomfort of drivers and passengers caused by frequent or top-speed adjustment is avoided; in addition, because the interval ofthe extracted instant pictures is moderate, processed data cannot be too large, and thus the microprocessor cannot bear too large burden under the condition that lane keeping is guaranteed.
基于图像识别的车道保持辅助方法。在车辆多方位安装高清摄像头,并将视频数据实时传送至数据库,视频转换模块根据高清视频间隔一定时间提取瞬间画面并以图片格式另存;微处理器提取瞬间画面并按时间顺序进行前后对比,根据设定的对比条件进行比对,具体根据行车速度及变化绝对值进行综合评估;当认定为车道偏离后,微处理器根据偏离方向和行驶速度计算调整方案并发送命令至方向盘电子助力系统,方向盘电子助力系统根据调整命令调整方向盘。本发明可保证车道正常且不会过于频繁或极速调整而导致驾乘人员的不适感,另外因为提取瞬间画面间隔适中,如此处理数据不会过大,微处理器在保证车道保持的情况下不至于负担过大。
