Abstract

The invention relates to a RTK (Real-time kinematic) tilt measurement accuracy detection method and system, computer equipment and a computer storage medium. The above RTK tilt measurement accuracy detection method comprises steps: RTK tilt measurement data acquired for RTK tilt measurement for a measurement target point are acquired; a distance resection adjustment model is constructed accordingto the RTK tilt measurement data, and a design matrix, a prior variance matrix and an observation value-calculation value vector are determined, wherein the distance resection adjustment model is a model for characterizing geodetic coordinate series residual data and variance data; and according to the prior variance matrix and the observation value-calculation value vector, the position accuracyof a measurement target point is calculated, a geometric accuracy factor is calculated according to the design matrix, and the measurement target point coordinate estimation accuracy is detected according to the position accuracy and the geometric accuracy factor. On the basis of ensuring high-accuracy RTK tilt measurement data extraction stability, and the high-accuracy measurement target point coordinate estimation cost is reduced.

Description

technical field [0001] The invention relates to the technical field of RTK measurement, in particular to an RTK tilt measurement accuracy detection method and system, computer equipment, and computer storage media. Background technique [0002] High-precision GNSS (Global Navigation Satellite System, Global Navigation Satellite System) dynamic positioning mainly uses RTK (Real-time kinematic, carrier phase difference technology) positioning technology, and the real-time dynamic positioning accuracy can reach centimeter level. RTK positioning directly determines the position of the GNSS receiver antenna phase center, and the position of the measurement target point needs to be transmitted by the antenna phase center position according to the spatial geometric relationship between the two. During the traditional RTK operation, it is required to center the circular level bubble on the centering rod to ensure that the centering rod is perpendicular to the horizontal plane where ...
