单目视觉的车辆安全速度的研究

The study of the vehicle safety speed based on monocular vision

为提高车辆行驶的安全性,我们利用道路识别的距离来判断和控制车的安全速度。该方法是基于单目视觉的直线智能车辆道路识别模型,首先将采集的道路图像进行预处理,然后利用Sobel算子进行道路标线识别和提取最后利用透视变换消除透视投影对道路识别的影响。根据处理后的图像计算识别到的距离,最后根据识别距离、安全距离和制动距离计算安全行驶速度。

In order to improve the safety of the vehicle, we use the distance of the road recognition to determine the safety and control vehicles speed. The method is based on monocular vision of intelligent vehicle straight road recognition model.First of all, collection of road image be preprocessed, and then we use the Sobel operator for road marking identification and extraction and the perspective collineation to eliminate the influence of perspective projection on road recognition.Calculate according to the processed image recognition to the distance, according to the recognition distance, safety distance and braking distance calculation safe driving speed.
