Embodiment Construction

[0026] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0027] The principle of the three-dimensional precision control network measurement method of the present invention is to use three total stations to measure each group of measurement objects in the conductors by using three consecutively adjacent conductor points in the planned conductors as a group of measurement objects, and Use the corresponding measurement data of the next group of measurement objects to compare with the measurement data of the same measurement object in the previous group. If the comparison result is not within the set range, immediately restart the measurement from the first group of measurement objects. If If the comparison result is satisfactory, the measurement of the next group of measurement objects will be carried out, and the comparison result will still be judged in the same way, and so on until all the measure...

Abstract

The invention, which belongs to the technical field of precision engineering measurement, relates to a three-dimensional precision control network measurement method. According to the method, three continuous adjacent wire points in a wire are used as a group of measurement objects; thee total stations are used for measuring each group of measurement objects in the wire; corresponding measurementdata of the next group of measurement objects are compared with measurement data of the previous group of same measurement objects; if the comparison result does not meet a set range, measurement is started again immediately by starting with a first group of measurement objects; and otherwise, measurement of the next group of measurement objects is carried out until all measurement points are measured completely. According to the measurement method provided by the invention, whether the measurement data are accurate or not can be compared in real time in the measurement process; and when the error of the measurement data of a certain group of measurement objects is large, measurement is started again directly from the first group of measurement points. The labor intensity of workers is relatively low; the measurement efficiency is high; the method is simple and efficient; and the high reliability of the measurement result can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of precision engineering measurement, and in particular relates to a measurement method for a three-dimensional precision control network. Background technique [0002] The measurement method of the three-dimensional precision control network in the prior art, by respectively fixing the corner cube on two total stations, by observing the corner cube when measuring, determines the relevant measurement information (including horizontal angle, vertical angle and oblique angle). distance), as shown in Figure 1(a), and the coordinates are transferred according to the wire. This method improves the accuracy of the elevation direction through the opposite observation, but only after all the traverse points on the traverse are measured, can it be found through inspection whether the error of the measurement data is too large, and when it is determined that the error of the measurement data is too large Re-measure a...
