基于Web3D的倾斜三维实景模型漫游系统实现

Implement of Oblique Photography 3D Model Visualization System Based on Web3D

针对目前倾斜三维实景的展示,只能局限在本机中浏览特定存储的场景及受众面窄等问题,在分析三维实景可视化关键技术的基础上,将倾斜摄影测量采集并重建的安徽财经大学三维实景模型,利用Cesium平台实现在浏览器上漫游和查询倾斜三维实景模型以及相关信息。该系统构建简单,使用户脱离专业设备和软件的限制,浏览查询更加方便,提高了倾斜三维实景模型的使用率。

In view of the display of oblique photography 3D model at present,it is limited to the speeifie scenes andaudiences. Based on the analysis ot the key technologies of 3D real-view visualization, this paper obtained the images of Anhui University of Finance and Economies and reconstructed the 3D model by oblique photogrammetry, and used the Cesium plattorm to navigate the 3D model and query the related information through the browser. The system is simple in construction and makes users break away from the limitation of professional equipment and software. What＇ s more, it is more convenient to be viewed and improves the usage rate ot oblique photography 3D models.
