Abstract

The measurement requirements for civil aircraft components when using laser radar are always large-scale, high precision, high efficiency and so on, so several measuring stations are needed to construct a large-scale measuring network. Thus how to set up the layout of the stations is very important as it has direct influence with the precision. In this paper we develop a layout optimization method to solve the question in order to meet the requirements for precision and efficiency. The math model of the optimization is constructed by using the precision as constraints, and the solution is given to get the exact number and division of the laser radar. The initial layout can be obtained by the region growing algorithm to carry on the characteristics of discrete information and extract the discrete point method. And then we use the measurement uncertainty to optimize the results and the division. The experimental results show that compared with the experience-based manual layout, this method is more feasible and effective in obtaining large range and small number of measurement area division results and reasonable stations measurement stations. This experiment has verified the rationality, the correctness, the precision and effectiveness of the relevant methods.
