摘　　要：为解决实景影像在表达地理空间信息时无法实现地理实体单体化的问题,本研究提出一种面向VR的实景影像与三维地理要素融合方法。通过利用车载移动测量系统采集道路周边的点云及全景影像数据,生成可量测序列街景,实现实景数据空间化。进一步重构和编码三维地理要素,使其表达更为精简。最后,将空间化的实景影像数据与精简化三维地理要素进行融合,实现三维地理空间的直观、立体、要素化表达。研究结果表明,该方法能够有效地将实景影像与三维地理要素融合,为实景三维建设提供有益的借鉴。To solve the problem that real scene images cannot realize the individual expression of geographical entities when expressing geographical spatial information,this study proposes a method for integrating real scene images and 3D geographical elements for VR.By utilizing the vehicle-mounted mobile measurement system to collect point clouds and panoramic image data around the road,we generate measurable sequence streetscapes to realize spatialization of real scene data.Furthermore,we reconstruct and encode 3D geographical elements to make their expression more concise.Finally,we integrate spatialized real scene image data with simplified 3D geographical elements to achieve intuitive,stereoscopic,and elemental expression of 3D geographical spaces.The research results indicate that this method can effectively integrate real scene images with 3D geographical elements,providing useful references for the construction of real scene 3D.
