The method includes: acquiring three-dimensional contour data and grayscale data of a pavement on the basis of a line scanning three-dimensional measurement sensor; preprocessing the three-dimensional contour data and the grayscale data, where the preprocessing includes performing three-dimensional modeling according to the three-dimensional contour data to acquire three-dimensional modeling data and correcting the grayscale data; and extracting a key contour of each cross section in the three-dimensional modeling data, and performing pavement technical condition index detection on the pavement according to the three-dimensional modeling data, the key contour, and the corrected grayscale data to acquire a technical condition index of the pavement.",
