When a laser radar is used to measure large structural parts, it is often necessary to establish multiple measurement stations to construct a large measurement network, for which the station positions and the number of laser radars are key factors affecting the measurement results. A method for laser radar measurement planning of large structural parts is designed for large component contour measurements of large aircraft component. The measurement accuracy is considered as a constraint, and the method considers the number of measurement stations and the division results of measurement area as the evaluation target. Further, a measurement mathematical model reflects the characteristics of discrete information and establishes a discrete point method. Using the method of measurement station planning based on the region growing algorithm, the initial number and location of stations are determined. Moreover, measurement uncertainty optimization considering the division of the measurement area and results is adopted. Experimental results show that compared with experience-based manual measurement planning, the proposed method is more feasible and effective in performing large-area measurements with a small number of measurement area divisions and a reasonable number of measurement stations.
