摘　　要：对路面坑洞测量方法进行了研究,提出一种无参考物测量方法。利用安卓设备对坑洞进行图像采集并用其方向和重力感应参数对图像进行预处理和矫正,然后建立了坑洞测量的数学模型并给出计算公式,最后对测量方法进行了误差分析。实验结果表明,该方法测量准确,误差在可接受范围内。与传统测量方法相比,该方法有效地解决了依赖参考物测量的问题,对环境依赖性低,提高了信息采集的便捷性。A potholes measurement method without reference materials was proposed by researching the existing measuring methods. Firstly,the pothole images were photographed by using the Android devices,and then the direction and gravity parameters of it were utilized to pre-process and correct pothole images. Secondly,mathematical models to measure potholes were established and the formulas were calculated. Finally,the errors of the proposed method were analyzed. Experimental results show that the presented method can achieve high accuracy of measurement and its error is acceptable. Compared with the traditional measurement methods,the problem for relying on reference materials is solved,and it has low dependence on the environment; the more important thing is that the convenience of information collection is improved obviously.
