Embodiment 1
[0036] Such as figure 1 As shown, the present embodiment provides a total station-based plane normal astronomical orientation measurement method, comprising the following steps:
[0037] S1: Obtain the three coordinates of uniformly distributed points on the plane to be measured
[0038] Set the coordinate system established by the total station as the world coordinate system, use the total station to measure the uniformly distributed points on the plane to be measured, and obtain the three coordinates of these points;
[0039] S2: Calculate the pitch angle of the plane and the horizontal azimuth angle in the coordinate system of the total station
[0040] Transfer the three coordinates of each point obtained in the above step S1 to the computer, use the application program written based on Mtalab software to apply the principle of least squares to fit the plane formula, obtain the plane normal vector, and then calculate the plane normal vector in the whole station The horiz...
Embodiment 2
[0053] Such as image 3 As shown, as shown in the astronomical orientation schematic diagram of the present invention, N is the north celestial pole, and the sun σ is observed at the observation point M (total station setting point), and the position of the observation sun moment is calculated by the solar ephemeris model, and the sun σ and The angle A between true north. Measure the horizontal angle β between the sun σ and the target object B (in this system, MB refers to the normal vector of the plane to be measured) by the total station. At this time, the angle between the target object B and the true north is a=A+β.
[0054] In summary, the plane normal astronomical orientation measurement method and system based on the total station in the above two groups of embodiments, because the total station is used to replace the traditional theodolite to carry out the orientation measurement to the plane, it can make the orientation measurement process It is simpler and easier to...
