Systematic Evaluation and Optimization of Unmanned Aerial Vehicle Tilt Photogrammetry Based on Analytic Hierarchy Process

In the data acquisition and processing of Unmanned Aerial Vehicle(UAV) oblique photography monomer modeling, it is hard to balance the model quality and the production efficiency. This research applied the Analytic Hierarchy Process (AHP) evaluation method in the field of systems engineering to the management and decision of UAV oblique photography monomer modeling. Firstly, the AHP model is constructed by the expert survey method, and the relative weights of 6 evaluation indicators in the first hierarchies and the comprehensive ones of 3 in the second hierarchies are calculated. Then, each index data of different photo modeling schemes were collected and processed through experiments, and the AHP model was used to systematically evaluate each modeling scheme. Finally, the quadratic function is constructed with two variables, the number of photos and the AHP system score, meanwhile obtaining the optimal scheme by calculation. This is a useful attempt to apply the scientific evaluation method in the field of systems engineering to the production management of UAV aerial surveys. In this way, the efficiency of internal and external data collection and processing can be maximally improved while guaranteeing modeling accuracy.
