Road sideline detection method and device

The invention provides a road sideline detection method and device, which relates to the technical field of image processing. The roadside detection method is applied to a user terminal that is connected to a camera, and the camera is fixedly mounted on the edge of the vehicle body. The method comprises the following steps: obtaining an image of a road including a body edge taken by a camera; converting the image into a gray-scale image; converting a gray image into a binary image; identifying a road sideline in a binary image; based on the position of the road sidelines in the binary image, obtaining the distance between the vehicle body edge and the road sidelines. The method and device for detecting road sidelines provided by the invention can effectively reduce the cost of detecting road sidelines, has the detection accuracy, and can be widely applied to a motor vehicle driver examination system and a driving simulation system. 本发明提供了种道路边线检测方法及装置，涉及图像处理技术领域。道路边线检测方法应用于与相机通信连接的用户终端，相机固定安装于车身边缘，该方法包括：获得相机拍摄
