Full-width structure depth detection method based on precise three dimensions
The invention relates to the technical field of road surface detection, and provides a full-width structure depth detection method based on precise three dimensions, which comprises the following steps: receiving original road surface elevation data and original road surface gray scale data of each measuring point on a road acquired by a line scanning three-dimensional measurement sensor, the measurement range of the line scanning three-dimensional measurement sensor covering the whole lane width; extracting target pavement elevation data and target pavement grayscale data in the lane range from the original pavement elevation data and the original pavement grayscale data; reconstructing pavement three-dimensional point cloud data based on the target pavement elevation data and the target pavement grayscale data; and on the basis of the reconstructed pavement three-dimensional point cloud data, combining a preset pavement structure depth calculation model to determine the pavement full width structure depth. The measurement range of the line scanning three-dimensional measurement sensor covers the width of the whole lane, and data interference of the lane line and the edge of the lane line is removed, so that the finally measured construction depth can comprehensively and accurately reflect the full-width construction depth condition of the road surface.
本发明涉及路面检测技术领域，提供一种基于精密三维的全幅构造深度检测方法，包括：接收线扫描三维测量传感器获取的道路上各测点的原始路面高程数据和原始路面灰度数据，线扫描三维测量传感器的测量范围覆盖整个车道宽度；从原始路面高程数据和原始路面灰度数据中提取车道范围内的目标路面高程数据和目标路面灰度数据；基于目标路面高程数据和目标路面灰度数据，重建路面三维点云数据；基于重建的路面三维点云数据，结合预设的路面构造深度计算模型，确定路面全幅构造深度。本发明由于线扫描三维测量传感器的测量范围覆盖整个车道宽度，且去除了车道线及其边缘的数据干扰，因此，最终测量的构造深度能够全面且准确地反映路面全幅构造深度情况。
