The invention relates to the technical field of detection, and discloses a method and a system for detecting the flatness of highway bridges. The detection method includes the following steps: Step 1: Scanning the subgrade surface of the highway bridge to be measured by using an unmanned aerial vehicle system, and obtaining three-dimensional data of the subgrade surface of the highway bridge , establish a three-dimensional model of the road and bridge subgrade to be tested; Step 2: Set the running route of the detection trolley, and calibrate several data collection points at equal intervals on the preset travel trajectory as the target position in the travel trajectory of the detection trolley; Step 3: The detection trolley moves along the preset travel trajectory, and when it moves to the nth data collection point, obtains the elevation data of this point; Step 4: Upload the obtained elevation data of each data collection point to the processing system Compensation calculation is performed. The invention does not need manual on-site detection, improves the detection efficiency, and improves the precision measurement accuracy through the compensation and correction process of the detection data.
Description
technical field [0001] The invention relates to the technical field of detection, in particular to a method and system for detecting the flatness of highway bridges. Background technique [0002] Highway bridge inspection includes inspection and verification of bridge structure, as well as bridge load test and measurement, among which bridge deck flatness inspection is one of them. [0003] The existing road and bridge flatness detection adopts manual detection. The artificial selection of detection points and manual detection cannot accurately reflect the smoothness of the road surface, nor can the detection data be compensated and corrected, resulting in the difficulty of ensuring the accuracy of the flatness detection. Therefore, the present invention provides a method and system for detecting the smoothness of highway bridges, which can compensate and correct the detection data and ensure the detection accuracy. SUMMARY OF THE INVENTION [0004] The purpose of the pre...
