Automatic baseline measuring system

Abstract

The invention discloses an automatic baseline measuring system comprising a casing, a data processing and control module arranged inside the casing and a positioning module electrically connected with the data processing and control module. In addition, the automatic baseline measuring system also consists of an optical distance measuring module, an angle measuring module, a measuring data display module and / or a measuring data interface module that are connected with the data processing and control module electrically. The positioning module transmits obtained latitude and longitude information and the like to the data processing and control module; the optical ranging module measures distance information and transmits the information to the data processing and control module; and the angle measuring module measures attitude values like an azimuthal angle and a pitching angle and transmits the values to the data processing and control module. According to the invention, data fusion is carried out on latitude and longitude information, the attitude values and the distance data; and when the distance between two points is measured, range finding is carried out by using the principles of optics directly instead of using the geographic coordinate calculation. Moreover, the efficiency is high and the error is small.

Description

technical field [0001] The invention belongs to the technical field of information control, and in particular relates to an automatic baseline measurement system. Background technique [0002] Baseline measurement refers to the precise measurement of the absolute position information between two points in the geographic coordinate system. Here, the absolute position information refers to the azimuth, elevation angle, distance and distance between a certain point in the geographic coordinate system and the determined point. The sum of longitude, latitude, elevation and other information. Accurate measurement baseline is the key to realize accurate information control and information fusion. [0003] At present, the more advanced baseline measurement technology in the existing technology is: GPS or BDS baseline measurement, its principle is: use GPS or BDS positioning device to measure the geographical coordinates of two points; Coordinates in the geocentric system; establis...

AI Technical Summary

Problems solved by technology

[0007] (3) This measurement scheme uses measurement plus calculation to obtain baseline information, which is inefficient and time-consuming

[0008] (4) This measurement scheme has no information output interface, and the acquired location information cannot be directly used by a third party as an information source
