Survey station layout intelligent optimization method of spatial measurement positioning system

Abstract

A survey station optimization deployment problem is one of important problems in use of a spatial measurement positioning system. The present invention provides a survey station layout intelligent optimization method of a spatial measurement positioning system, so that an optimized survey station layout can fully cover a tested area under certain costs and a requirement of measurement accuracy can be met. According to the present invention, a proper positioning error model is established from three aspects of constraint analysis, optimization objective, and optimization means, a multi-goal optimizing function is defined, and survey station layout optimization of the spatial measurement positioning system is implemented by using a practical intelligent optimization algorithm. According to the survey station layout intelligent optimization method of a spatial measurement positioning system, a survey station network optimization deployment problem of the spatial measurement positioning system in an engineering application is effectively resolved. As a quantity of survey stations increases, the method has good expansibility, provides a new method for a multi-station networking measurement layout optimization problem based on an angle intersection principle, and has important theoretical value and practical significance.

Description

technical field [0001] The invention belongs to the technical field of large-scale three-dimensional coordinate measurement on industrial sites, and in particular relates to an intelligent optimal deployment method for a station of a multi-station network measurement system, and in particular to an intelligent optimization method for station layout of a space measurement and positioning system. Background technique [0002] In large-scale engineering measurement, the measured object not only has a large geometric size, but also requires high relative measurement accuracy (better than 10ppm), a large number of key points to be measured, multiple measurement tasks coexist, and is greatly affected by the external environment. Therefore, measurement methods and usage All measuring tools are unique. The network multi-station measurement system has great potential to balance the contradiction between measurement range, measurement accuracy and measurement efficiency, and provides ...
