Pavement performance determination method and system based on pavement texture
The invention provides a pavement performance determination method and system based on pavement texture. The method comprises the following steps: acquiring a to-be-detected pavement image; determining image coordinates and elevation data of each pixel point in the to-be-detected pavement image; according to the image coordinate of each pixel point in the to-be-detected road surface image, dividing the to-be-detected road surface into a plurality of textures; determining feature data of each texture in the to-be-detected pavement according to the elevation data; according to the deviation coefficient and the distribution coefficient, determining a direction feature type of each texture in the to-be-detected pavement; according to the roughness coefficient, determining a rough feature type of each texture in the to-be-detected pavement; and determining the performance of the to-be-detected pavement according to the direction feature type and the rough feature type of each texture in the to-be-detected pavement. According to the method, the deviation coefficient, the distribution coefficient and the roughness coefficient are calculated, so that the direction feature type and the roughness feature type of each texture in the to-be-detected pavement can be accurately determined, and the accuracy of pavement property determination is further improved.
本发明提供了一种基于路面纹理的路面性能确定方法及系统，方法包括获取待测路面图像；确定待测路面图像中每个像素点的图像坐标和高程数据；根据待测路面图像中每个像素点的图像坐标，将待测路面划分为多条纹理；根据高程数据，确定待测路面中每条纹理的特征数据；根据偏离系数和分布系数，确定待测路面中每条纹理的方向特征类型；根据粗糙系数，确定待测路面中每条纹理的粗糙特征类型；根据待测路面中每条纹理的方向特征类型和粗糙特征类型，确定待测路面的性能。本发明通过计算偏离系数、分布系数和粗糙系数，能够准确确定待测路面中每条纹理的方向特征类型和粗糙特征类型，进而提高路面性质确定的准确性。
