Mobile pavement detection method and system based on laser light source

The invention provides a mobile pavement detection method and system, and the method comprises the steps: employing a laser light source to irradiate a pavement, and obtaining a color image under a visible spectrum and a gray level image under an infrared spectrum, which are obtained through photographing the pavement by a multispectral camera; detecting the color image to obtain a pavement pollution area; detecting the grayscale image to obtain a pavement pollution area and a pavement foreign matter area; extracting sub-regions corresponding to the pavement pollution region and the pavement foreign matter region from the color image to form a four-channel image; inputting the four-channel image into a preset classification identification network; and obtaining an identification result output by the classification identification network. The method improves the single detection coverage area. 本发明提供了移动式道面检测方法及系统，方法包括采用激光光源照射道面，获取多光谱相机拍摄该道面获得的可见光谱下的彩色图像和红外光谱下的灰度图像；对所述彩色图像进行检测，获得道面污染区域；对所述灰度图像进行检测，获得道面污染区域和道面异物区
