“…Workspace measuring and positioning system (wMPS) is a newly multi-station measuring system, of which the principle is similar to the theodolite. Since it has great potential to balance the contradictions between measurement range, measurement accuracy and measurement efficiency, it is the research focus and important development direction in large-scale engineering measurement [1][2][3][4] . The prototype physical of wMPS mainly consists of transmitters, receivers, vector probe and scale bar which are shown in Fig.…”

Workspace measuring and positioning system (wMPS) is a kind of large-scale and multi-station intersection system, of which the station layout optimization is a common but important problem. Station optimal topological geometry based on genetic algorithm was proposed in this paper. Firstly, the positioning error, coverage area and cost were taken as objectives to establish the multi-objective optimization function. Secondly, genetic algorithm optimization process was established according to multi-objective function. Thirdly, simulation analysis for layout optimization algorithm of 2-4 stations was performed. The results show that the proposed method is able to quickly converge to optimal solutions, have good adaptability and improve wMPS measuring performance as well.
