Full-width flatness detection method based on three-dimensional road surface
The invention provides a full-width flatness detection method based on a three-dimensional road surface, and belongs to the technical field of road detection. The method comprises the following steps: acquiring original elevation data of a road surface; establishing a three-dimensional pavement model according to the original elevation data, wherein the three-dimensional pavement model is used for representing the elevation of each position point in the pavement; performing region division in the three-dimensional pavement model to obtain a plurality of sub-regions, wherein the width and length of each sub-region are within a preset numerical interval, and the combination of the plurality of sub-regions covers the measured breadth of the pavement; for each sub-region in the plurality of sub-regions, calculating the flatness index of each sub-region by using a preset calculation method; and determining the full-width flatness of the calculation unit based on the flatness index of each sub-region, wherein the full-width flatness comprises the maximum flatness, the flatness mean value, the first wheel track flatness, the second wheel track flatness and the weighted flatness. According to the invention, the flatness condition of the road under the whole measurement breadth can be represented.
本申请提供一种基于三维路面的全幅平整度检测方法，属于道路检测技术领域。该方法包括：获取路面的原始高程数据；根据原始高程数据建立三维路面模型，三维路面模型用于表征路面中各位置点的高程；在三维路面模型中进行区域划分，得到多个子区域，其中，各子区域的宽度和长度分别处于预设的数值区间内，且多个子区域的组合覆盖路面的测量幅宽；对多个子区域中的每个子区域，利用预设计算方法计算每个子区域的平整度指数；基于每个子区域的平整度指数确定计算单元的全幅平整度，全幅平整度包括：最大平整度、平整度均值、第一轮迹平整度、第二轮迹平整度和加权平整度。本申请可以表征整个测量幅宽下道路的平整度状况。
