The invention discloses a method for detecting a highway pavement width. A camera is arranged in a vehicle and is used for detecting the width of the highway pavement. The method comprises the following steps of A, acquiring a highway pavement image, and acquiring the highway pavement image in front of the vehicle through a camera in the vehicle; B, detecting a lane line, detecting the acquired image through a deep learning image processing technology, and identifying lane information; C, converting a lane line coordinate, performing corresponding projection conversion and coordinate conversion on the lane line by combining internal and external parameters and an installation position of the camera to obtain world coordinates; and D, calculating the width of the highway pavement between the lane lines through the world coordinates. The highway pavement width is detected through an image processing mode, other auxiliary equipment and means are not needed, and the highway pavement widthcan be detected more accurately and quickly so that measurement efficiency is improved.
本发明公开了一种检测公路路面宽度的方法，将摄像头设置于车辆内部，用于检测公路路面宽度，具体方法包括以下步骤：步骤A、采集公路路面图像，通过车内的摄像头采集车辆前方的公路路面图像；步骤B、车道线检测，通过深度学习图像处理技术对采集的图像进行检测，并识别出车道信息；步骤C、车道线坐标转换，结合摄像头的内外参数及安装位置，对车道线进行相应的投影转换和坐标转换，得到世界坐标；步骤D、通过世界坐标计算车道线之间的公路路面宽度。本发明通过图像处理方式对公路路面宽度进行检测，无需其他辅助设备和手段，能够更加准确快速的对公路路面宽度进行检测，从而提高测量效率。
