Embodiment

[0014] See figure 1 , figure 2 , The specific steps of this embodiment are:

[0015] Place the theodolite 1 through the tripod 2 above the base point D during measurement and level it in the middle. Point A is the intersection of the horizontal axis and the vertical axis of the theodolite 1, and the tower ruler 3 with vertical level bubbles is placed one distance from the theodolite 1. Adjust the position of the meter to the vertical, keep the tower ruler 3 parallel to the vertical axis of the theodolite 1, and then adjust the theodolite 1 to the level, and mark the projection line of the theodolite 1 objective cross wire on the tower ruler 3 and the tower ruler 3 intersection point B, and then place a flat mirror 4 with a diameter of 10 cm on point B on the tower ruler 3. The flat mirror 4 slowly slides down from point B, and the theodolite 1’s line of sight slowly moves down with the flat mirror 4, when the theodolite 1 eyepiece can be When the image formed by point D in the ...

Abstract

The present invention discloses a method for measuring the height of a theodolite. According to the method, the light reflection principle is used, a vertical stadia rod is established a certain position away from a measuring base point after the theodolite is subjected to centering leveling on the measuring base point, a light reflection body is placed on the stadia rod, the base point image formed in the light reflection body can be observed from the theodolite eye lens through the movement of the light reflection body up and down along the stadia rod, and the distance between the theodolite horizontal axis to the base point can be calculated through the light incident angle and the reflection angle equal relationship and the included angle relationship between the light incident angle and the parallel line, wherein the distance is the height of the theodolite. The method of the present invention has advantages of simple and clear principle clear, simple and cheap material, simple operation, high precision, easy grasping, and easy engineering use.

Description

Technical field [0001] The invention belongs to the technical field of engineering measurement, and particularly relates to a method for measuring the height of a theodolite. Background technique [0002] The current method of measuring the height of theodolite instrument is mainly to use a steel ruler to directly measure the distance from the base point to the side of the theodolite, and then obtain the height of the instrument through a certain triangulation transformation. This method has a large measurement error and a large influence of human factors, which cannot meet the high precision requirements of engineering measurement. Summary of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a method for measuring the height of the theodolite. [0004] The idea of ​​the present invention: using the principle of light reflection, the distance between the horizontal axis of the theodolite and the base point can b...
