Method for establishing self-adaptive control network

Abstract

The invention discloses a method for establishing a self-adaptive control network, which comprises the following steps of: 1, setting at least three reference network points with known coordinates, and setting measuring points or a combination body of the measuring points and an observation station on the reference network points; 2, arranging the combination body which is in intervisibility withat least three reference network points, controlling a measurement station to emit laser for scanning, calculating coordinates of the combination body according to reflected laser signals and the reference network points, and then taking the combination body as a new reference network point; 3, repeating the step 2, re-laying the combination body, and forming new reference network points until allthe new reference network points are laid; and 4, controlling measurement stations of all the new reference network points to perform laser scanning, correcting coordinates of all the new reference network points according to a scanning result, and completing establishment of the control network after correction. According to the invention, the position information of the new reference network point can be rapidly obtained and adaptively corrected, and the anti-interference capability and the data precision of the control network are greatly improved.

Description

technical field [0001] The invention relates to the field of measurement technology, in particular to a method for establishing an adaptive control network, which is mainly used in industries that need to locate targets. Background technique [0002] The planar control network is to form a network of geodetic control points with a certain form of graphics, measure the coordinates of the network points, or calculate the coordinates of the network points by measuring the angle, side length and azimuth angle in the network. Traverse measurement is often used in the establishment of plane control networks in small areas, especially in building areas with complex distribution of ground features, hidden areas with many visual obstacles, and strip areas. [0003] The current control network survey is mainly performed by total stations, theodolites or GPS, all of which require a large number of survey professionals to complete and require regular review. The main technical difficul...
