Research on high precision 3D model reconstruction of consumer inclined UAV

针对多镜头测绘级无人机构建实景三维模型价格昂贵、技术门槛较高等问题,提出消费型倾斜无人机高精度三维模型构建方法。该方法利用消费型无人机结合倾斜摄像相机采集多视影像数据,分别探讨了针对多视影像数据特点的影像匹配方法、引入曝光延迟模型的光束法区域平差算法以提高多视影像的定位信息以及实景三维构建等关键技术;最后,通过实际工程验证了该方法的可行性,为小区域高精度的实景三维模型构建提供一种思路。

In order to solve the problems of high cost and high technical threshold for constructing real scene 3 D model of multi shot mapping UAV, a high-precision 3 D model reconstruction method for consumer tilt UAV is proposed. This method uses consumer UAV and tilt camera to collect multi view images and explore the image matching, beam area adjustment algorithm with exposure delay model to improve the positioning information, and 3 D construction of real scene. Finally, the feasibility of this method is verified by practical engineering, which provides a solution for 3 D model construction of small area.
