Abstract

Abstract: Aiming at the current problems of high work intensity, low mapping efficiency, and difficult to measure elements, this paper proposes an auxiliary photovoltaic roof area measurement method based on UAV tilt photogrammetry. This paper studies on oblique photography, three-dimensional modeling, mapping and evaluates the accuracy of the measurement results. The results show that the RSME of three-dimensional model in the plane position is 3.9 cm, the error in the elevation is 4.3 cm, the error in the corner of the building is 4.3 cm, the error in the side length of the building is 3.1 cm, and the area of the building is smaller than the second-level tolerance accuracy of the urban commercial building, all the accuracy detected in the case meets the requirements of national standards, so it is feasible to use this method to measure the area of photovoltaic roofs.

Key words: UAV oblique photography, real scene 3D model, photovoltaic resources, POS system, adjustment
