Railway track measuring method
The invention discloses a railway track measuring method. The method comprises the following steps: determining an attitude angle of mobile equipment in a three-dimensional direction at a current sampling moment; fusing a first GNSS antenna center coordinate obtained in real time with a second GNSS antenna center coordinate measured by an inertial navigation sensor, and converting a target GNSS antenna center coordinate obtained through fusion into a PPK rail center coordinate; accumulating the PPK rail center coordinates and IMU coordinates determined at the current sampling moment according to the attitude angle of the mobile equipment in the three-dimensional direction to obtain rail center line measurement coordinates at the current sampling moment; and when entering the next sampling process, repeatedly executing the step of determining the attitude angle of the mobile equipment in the three-dimensional direction until all the sampling processes are ended, and determining the advancing track of the railway track according to the track center line measurement coordinates calculated in each sampling process. According to the method, the railway track measurement efficiency can be improved, and the method well adapts to the actual application scene of track measurement.
