Problems solved by technology

[0004] However, the above-mentioned astronomical directional measurement method still has certain deficiencies in use. The degree of automation of the astronomical directional measurement method is not high enough to meet the automation and informatization requirements of the measurement, and the measurement accuracy is sometimes difficult to achieve. requirements, which is not conducive to the measurement and orientation work, therefore, a method and system for plane normal astronomical orientation measurement based on total station is proposed

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...

Abstract

The invention discloses a plane normal astronomical orientation measurement method and system based on a total station, belonging to the technical field of astronomical navigation, comprising the following steps: S1: obtaining the three-coordinates of uniformly distributed points on the plane to be measured; S2: calculating the plane Pitch angle and horizontal azimuth in the coordinate system of the total station; S3: Find the angle between the sun and true north. The present invention carries out directional measurement to plane owing to adopting total station to replace traditional theodolite, can make directional measurement process simpler like this, easy to operate; And adopt latest solar ephemeris model and precession-nutation model in the system, make The accuracy of the position of the star reaches the milliarcsecond level, and the azimuth angle of the true north of the plane normal and the elevation angle of the plane can be easily measured; the application program based on the Mtalab software is also used to calculate and process the collected data, which makes the system more automatic Greatly improved, it can meet the automation and informatization requirements of measurement.

Description

technical field [0001] The invention relates to the technical field of celestial navigation, in particular to a method and system for measuring plane normal astronomical orientation based on a total station. Background technique [0002] In the current geodesic astronomical surveying work, a new type of astronomical positioning and orientation system based on satellite timing devices, high-precision electronic theodolites and computer processing terminals has been developed in the existing technology. , adjustment calculation, results report and other functions, can be used for astronomical latitude and longitude and azimuth, vertical line deviation measurement, meridian, gyroscope calibration and other work. [0003] The measurement principle is mainly to use the theodolite to measure the horizontal azimuth of the target point, and then measure the horizontal azimuth of the sun and record the measurement time at the same time. According to the positioning triangle, the angl...
