Embodiment Construction

[0037] Using the total station to optimize the method of triangular elevation measurement, the steps are as follows:

[0038] If we can place the total station at any point like a level instead of placing it on a known elevation point, and at the same time use the triangular elevation measurement principle to measure the height to be measured without measuring the height of the instrument and the height of the prism. point elevation, the speed of measurement will be faster. Such as figure 1 , assuming that the elevation of point B is known, and the elevation of point A is unknown, here the elevation of other points to be measured shall be measured by a total station. Firstly, it can be known from formula (1):

[0039] h A =H B -(Dtanа+i-t) (2)

[0040] In the above formula, i and t are all unknown except that the value of Dtanа, that is, V can be directly measured by an instrument. But one thing is certain, that is, once the instrument is set up, the value of i will rema...

Abstract

The invention relates to a method for optimizing trigonometric elevation measurement by using a total station. The method comprises the following steps: 1, the instrument is put at any point, whereinthe selected point position is required to be visible to a known elevation point; 2, the known elevation point is collimated by the instrument, the value of V is measured, and the value of W is calculated; 3, the elevation of the measuring station of the instrument is reset to be W, and the instrument height and the prism height are set to be 0; and 4, a to-be-measured point is aimed to measure the elevation. Through long-term exploration, a new method is summarized for triangulation height measurement. The method not only combines the characteristics of any station for leveling measurement, but also reduces the error source of the trigonometric elevation, and does not need to measure the instrument height and the prism height in each measurement. The triangulation height measurement precision is further improved, the measurement speed is high, and the measurement speed is high.

Description

technical field [0001] The invention relates to the field of engineering construction surveying and mapping, namely a method for optimizing triangular elevation measurement by using a total station. Background technique [0002] In the prior art, the calculation of elevation is one of the indispensable and important tasks in the surveying work, and elevation measurement is often involved in the construction process of the project. There are two methods of leveling surveying and triangular elevation surveying in the historical and traditional surveying methods. Although these two methods have their own characteristics, they both have shortcomings. Leveling is a direct method of height measurement, which requires a high degree of accuracy in determining height differences. However, leveling is limited by terrain fluctuations, and the workload in the field is large, and the measurement speed is slow. Triangulation elevation measurement is an indirect method of height measureme...
