摘要
通过研究肉眼分辨物体表面不平度的特性和数字图像技术 ,开发了应用数字图像技术评价和测量沥青路表面构造深度的方法 .该方法采用普通数码相机纪录道路表面构造特征 ,由图像的像素值分析得出路表面构造深度测量结果 .与常规方法的比较表明 ,该方法精度高、操作简便、成本低廉 。
By studying the characteristics of the surface rou ghness differentiate d by the eye and the digital image technique, a method of evaluating and measuri ng pavement surface texture depth utilizing digital image technique was presente d. With this method, the pavement surface roughness can be recorded by an ordina ry digital camera, and the pavement texture depth can be obtained by the pixel a nalysis of recorded images. Compared with the conventional methods, the method p roposed here is simple and easy to apply. It is a promising method for evaluatin g and measuring the pavement surface performance with higher precision and lower cost.
