倾斜摄影影像与实景三维模型精确融合技术研究与实现

Research and Implementation of Precise Fusion Technology between Oblique Photographic Image and Real 3D Model

针对实景三维模型表面空洞、凹凸不平、存在空中悬浮物、大比例尺下显示模糊和精度不高等问题,提出了倾斜摄影影像与实景三维模型精确融合技术,建立影像与实景三维模型在计算机窗口下的几何对应关系,在大比例尺下用影像精准叠加在实景三维模型上,研究实现在三维漫游操作过程中影像与实景三维模型无缝切换显示。该技术应用于荆州市三维规划辅助决策系统中,为规划提供了较好的现实展示效果。

In general,there is hollowness,uneven surface and suspended solids in real 3D model.Real 3D model is fuzzy in large scale.Precise fusion technology between oblique photographic image and real 3D model is designed.By the technology,the geometric correspondence relationship is established between the image and real 3D model in the computer window coordinate system.The image is accurately overlaid on real 3D model in large scale.In the 3D scene,the image and real 3D model can switch seamlessly.This technology is applied in the Jingzhou 3D planning decision support system,which provides a good realistic display effect for the planning.
