Road cross slope measurement method based on triangulated irregular network

The invention discloses a road cross slope measurement method based on a triangulated irregular network, and the method comprises the steps: fitting a road axis and a road side line of a to-be-measured road into a topographic map, constructing a triangulated irregular network model according to the topographic map, and enabling the triangulated irregular network model to have three-dimensional coordinates of any point on a road plane, and the gradient from the road axis to the road side boundary is calculated by using the coordinate, so that the measurement accuracy can be improved, and the calculation workload can be reduced, thereby effectively solving the defects of large workload and certain error in the prior art. 本发明公开了一种基于不规则三角网的道路横坡测量方法，通过将待测量道路的道路轴线和道路边线拟合至地形图中，依据地形图构建一个不规则三角网模型，该不规则三角网模型上已经有了道路平面上任意一点的三维坐标，用该坐标计算得出道路轴线至道路边线的坡度，既能够提高测量的准确度，也能够降低计算的工作量，从而有效解决了现有技术所存在的工作量较大和存在一定误差的缺陷。
