A method of establishing an adaptive control network

Abstract

The invention discloses a method for establishing an adaptive control network, comprising: 1: setting at least three reference network points with known coordinates, and setting measuring points or a combination of measuring points and measuring stations on the reference network points; 2: laying out Combined body, the combined body has at least three reference network points, control the station to emit laser for scanning, calculate the coordinates of the combined body according to the reflected laser signal and the reference network point, and then use the combined body as the new reference network point; 3: Repeat steps 2. Arrange the combination again and form a new reference network point until all new reference network points are laid out; 4: Control the measuring station of all new reference network points to perform laser scanning, and correct the coordinates of all new reference network points according to the scanning results, After the correction, the establishment of the control network is completed. The invention can quickly obtain the position information of the new reference network point and self-adaptively correct it, and greatly improve the anti-interference ability and data accuracy of the control network.

Description

Technical field [0001] The present invention relates to the field of measurement technology, in particular to an adaptive control network to establish a method, mainly used in the industry where the target needs to be located. Background [0002] The plane control network is a certain form of graphic to form a grid of earth control points, determine the coordinates of the dots, or calculate the coordinates of the dots by measuring the angle, edge length and azimuth angle in the net. Wire surveying is often used in the establishment of small area plane control networks, especially in building areas with complex feature distribution, hidden areas with more line of sight obstacles and strip areas. [0003] Current control network measurements are performed primarily through total stations, theodolites, or GPS, all of which require a large number of measurement professionals to complete and require periodic review. The main technical difficulties in the current technical solution ar...

AI Technical Summary

Problems solved by technology

The main technical difficulties in the current technical solution are: 1. It requires the participation of measurement professionals, which is time-consuming and costly; 2. The measurement points in the control network require stability, and the construction cost of the measurement points is high; 3. The measurement points in the control network Regular review is required, the operation efficiency is low, and the reliability of the entire control network is low
