Abstract

The invention relates to industrial field large-size measuring methods and provides a mobile launch station rapid orientation method based on a wMPS. Full-range measurement in various shielding areas is achieved, a high-precision measuring field is established, the average precision of the measuring field is improved, the problem of missing of the precision of part of areas of the measuring field is solved, and the method is adaptive to various severe environments and conforms to the tendency of current high-precision measurement. Thus, according to the technical scheme, the mobile launch station rapid orientation method based on the wMPS comprises the following steps that firstly, a plurality of fixed launch stations are arranged in a measuring space; secondly, with the combination of the measuring range of the launch stations, mobile stations are arranged near areas which are limited in measurement range or space and are about to be measured; thirdly, at least six global control points are selected in the measuring space; fourthly, receivers are arranged on the global control points; fifthly, the mobile stations are arranged at any place for coordinate measurement. The mobile launch station rapid orientation method based on the wMPS is mainly applied to industrial field large-size measurement.

Description

technical field [0001] The invention belongs to a large-scale measurement method on an industrial site, and in particular relates to a method for encrypting orienting a mobile station of an indoor space measurement system based on photoelectric scanning, expanding a measurement space and compensating for precision. Specifically, it relates to a fast orientation method of a mobile transmitting station based on a wMPS system. Background technique [0002] With the advancement of science and technology, large-scale space measurement is gradually developing towards high-precision positioning and large-scale measurement. Among them, the indoor space measurement system (wMPS: workshopMeasurement Position System) developed by the State Key Laboratory of Precision Measurement Technology and Instruments of Tianjin University has been widely used in the field of large-scale measurement, and has a large number of successful cases. The indoor space measurement system is a multi-station...
