Research on Rural Real Scene Model Measurement Based on POS Aerial Triangulation Technology

Abstract

Rural development has always been one of the key and difficult problems in China, such as rural natural disaster monitoring, rural land resources and homestead management, rural cultural and tourism development, comprehensive management of rural environment and so on. In this paper, POS aerial triangulation technology is combined with rural areas, and the three-dimensional rural real scene is modeled and digitized, which brings a new idea to rural development and governance. In this paper, the consumer UAV is used to complete the rural low altitude aerial photography, and the rural 3D model reconstruction is completed based on the smart3d platform. The specific principle of POS assisted aerial triangulation is analyzed and the three-dimensional modeling process based on UAV aerial photography is displayed. Through experiments, it is verified that POS assisted aerial triangulation technology without ground control points can realize the 1:1 establishment of three-dimensional real scene model. The side length and height information can be read on the model, and the accuracy is high. At the same time, it puts forward the possibility and convenience of three-dimensional real scene model for house and land ownership registration. In the scene of site constraints and topographic conditions, POS assisted aerial triangulation without ground control points has the application value of emergency rescue, and has a certain practical significance for rural geological disaster monitoring.
