specific Embodiment approach 1

[0028] Specific implementation mode one: the following combination figure 1 and figure 2 Describe the present embodiment, the centering method of the laser centering device under the control point of the theodolite described in the present embodiment, it realizes based on the laser centering device under the control point of the theodolite, and the laser centering device includes a vertical micro-laser 1, Housing 2, laser protection glass 3, glass fixing cover 4, four laser adjustment screws 5, power supply device 6, two positioning through holes 7 and power supply device rear cover 8,

[0029] The shell 2 is divided into a first section and a last section, the first section is cylindrical, and the last section is provided with a cavity along the direction perpendicular to the axis of the first section, and the cavity is connected with the inner cavity of the first section, and the inner cavity of the first section is arranged vertically along the axial direction. Micro lase...

specific Embodiment approach 2

[0035] Specific implementation mode two: the following combination Figure 1 to Figure 3 Describe this implementation mode, this implementation mode will further explain the implementation mode 1, and the step 1 described in this implementation mode is specifically:

[0036] Select a fixed point 1 above the room, set up a theodolite below the fixed point 1, turn on the vertical micro-laser 1 after the telescope of the theodolite is horizontal, and accurately level and align the center of the laser beam spot with the fixed point 1;

[0037] Then turn the theodolite aiming part to observe whether the center of the laser beam spot deviates from the fixed point 1:

[0038] If not, the beam direction of the vertical microlaser 1 coincides with the vertical axis of the theodolite; then perform step 2;

[0039] If so, correct the position of the vertical microlaser 1:

[0040] After rotating the collimator of the theodolite for 180 degrees, determine the center of the laser beam sp...

Abstract

The invention discloses a centering method of a laser centering device under a control point of a theodolite, belonging to the technical field of control point centering in the use of theodolite. The invention aims at solving the problems that the existing alignment between a theodolite and a measurement control point has low precision and the selection mode of the measurement control point is limited. The method is realized based on a laser centering device under the control point of a theodolite. The laser centering device comprises a vertical micro laser device, a shell, laser protection glass, a glass fixing cover, four laser device adjusting screws, a power supply device, two positioning through holes and a power supply device rear cover; and the centering method comprises the following steps: (I) overlapping the light beam direction of the vertical micro laser device and the vertical axis of the theodolite; and (II) performing laser centering under the control point of the theodolite. The method disclosed by the invention is applied to the centering under the control point of a theodolite.

Description

technical field [0001] The invention relates to a centering method of a laser centering device under a control point of a theodolite, and belongs to the technical field of centering a theodolite in use and a control point. Background technique [0002] In the underground engineering survey of theodolite, in order to avoid the damage of the survey control point, the survey control point is usually selected on the roof of the tunnel or roadway. During the measurement, in order to ensure the centering of the instrument, the vertical ball is hung on the measurement control point on the top plate to be centered with the theodolite. In this way, due to the large cross-section of the roadway, it is not convenient to hang the pendant ball when the roof is high; and the air flow in the roadway is large, the pendant ball will be in a swing state due to the influence of the wind flow, it is not easy to stabilize, and the accuracy of the centering will be affected. Reduced accuracy of ...
