Angle measurement method for highway bridge and culvert construction

The invention relates to the technical field of angle measurement data processing, in particular to an angle measurement method for expressway bridge and culvert construction, and the method comprises the steps: installing a plurality of inclinometers on a construction bridge and culvert column body, and constructing a noise interference value of each angle measurement data; analyzing the difference between each angle measurement data and the adjacent angle measurement data in the bridge and culvert angle measurement sequence, and obtaining the signal-to-noise value of each angle measurement data; obtaining the noise local intensity of each angle measurement data based on the distribution disorder degree of the signal-to-noise value of the local angle measurement data of each angle measurement data; and determining an adaptive filtering order of each angle measurement data in the bridge and culvert angle measurement sequence through the noise local intensity, denoising the angle measurement data in combinatio
