摘要
基于Ladybug3的全景可以呈现360度全视角的现实场景真实景观,为了方便地从全景影像中获取地物点的三维坐标,为观察者提供更丰富的信息,提出了一种通过提取地物点的水平方向角和垂直方向角,结合前方交会原理快速解算地物点三维坐标的方法。最后通过在特定场景自定义三维坐标系进行试验,验证了该方法的可行性。
Panorama based on Ladybug3 can render 360-degree viewing angle realistic scene and real landscape,in order to gain three-dimensional coordinates of the feature points from panoramic images and provide richer information to the observer. This paper presents a method which can quickly solve threedimensional coordinates of the feature points by extracting horizontal angle and vertical angle of feature points and combining with the principle of forward intersection. At last,it proves the feasibility of this method by testing in a particular scene by giving a custom three-dimensional coordinate system.
