摘要
针对载荷是无人机的一个重要指标参数,而目前市场所使用的倾斜相机存在因载荷太重影响无人机的性能,甚至导致一些型号的无人机无法搭载的问题,提出了2镜头摇摆倾斜相机,较好地平衡了载荷重量和建模效果。该倾斜相机最大的特点在于摇摆,通过镜头的摆动大大提升了2镜头相机的性能,把传统的2个角度的影像变成了6个角度的影像;6个角度的照片获取了非常详细的纹理信息,并且保证了重叠,解决了后期建模纹理缺少的问题。通过工程试验证明,利用2镜头倾斜相机获取的影像所建的三维模型,不论是从几何精度还是视觉效果,都能够满足很多应用需求。2镜头倾斜相机与常规5镜头相机相比,重量轻、结构更简单,获取的角度更多,成本更低,在三维建模应用方面有很大的优势。
Load of UAV is a very important parameter,at present,some oblique camera loads have affected UAV performance,and even lead to the problem that some types of UAVs cannot carry.Lightening the load of weight has been one of the key problems of UAV remote sensing.To resolve this problem,we developed the two cameras,which makes the load weight and modeling effects are well balanced.The biggest feature of the oblique camera is its swing.The performance of the two lens camera is greatly improved by swinging the lens,and it turns the traditional two angle images into six angles.Six angle photos can obtain very detailed texture information and enough overlap,solving the problem of modeling missing textures.Engineering tests prove the result:it is very good in geometric accuracy and visual effect.Compared with five cameras,two cameras is lighter,simpler structure,more angles images,and cheaper.It has great advantage in3D modeling application.
