摘要
针对目前可建设光伏屋顶面积实测工作强度大、成图效率低、要素难以测全等问题,本文提出了无人机倾斜摄影测量辅助光伏屋顶面积测算的方法。本文从倾斜摄影、三维建模、内业成图等方面进行研究,并对测量成果进行精度评定。结果表明,三维模型平面位置中误差为3.9 cm,高程中误差为4.3 cm,建筑物房角点中误差为3.1 cm,建筑物边长中误差为3.1 cm,房屋建筑物面积较差小于城市商品房二级精度面积限差,在案例中检测的各项精度均符合国家标准规范要求,因此本文方法用于可建设光伏屋顶面积测算是可行的。
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.
