    2015 年罗马教皇费城之旅的三维地图

    美国宾夕法尼亚州费城

项目概要

项目

负责罗马教皇到访活动规划的费城本地公司 ESM Productions (ESM) 委托 AEROmetrex 为这一历史性活动的复杂后勤工作进行工程设计。主办这一活动涉及大量规划工作,而且需要与地方和州管理机构以及美国特勤局进行协调。为了满足设置 56400 个活动需要的临时结构、周长 33 英里的安全路障的需求,应对当地道路封闭带来的影响,同时确保在规划过程中和活动期间保持交通顺畅并实现无缝沟通,ESM 需要全面、逼真、集成的三维建模和模拟软件。请观看此简短视频记录,了解该项目的范围和影响。

解决方案

澳大利亚测绘领导者 AEROmetrex 通过直升机拍摄了该城市的高分辨率航拍照片,并采用 Bentley ContextCapture(原 Acute3D)将底图和地面拍摄资料相结合,最终基于 28000 张数码照片构建出了细节丰富的三维贴图实景网格。该精确模型随后用于 MicroStation 中,作为在实景网格中所有临时设施和路障的详细布局和设计的基础。借助 LumenRT,项目团队生成了模型动画以模拟预期的运作体验并优化决策,以确保安全、成功地举办该活动。


成果

在这次万众瞩目、准备时间紧迫的活动中,Bentley 实景建模和模拟软件大幅降低了风险,改进了决策过程,提高了工作时效性并优化了效率,同时为有极高安全性要求的工作流提供支持。在该解决方案中,ESM 可以预测当地道路封闭所导致的影响,以便在该活动的整个规划过程中保持交通顺畅并实现无缝沟通。Bentley 软件的灵活性、互操作性和准确性使之更快地得到了利益相关方的认可,确保了这一全国最盛大公共活动之一的成功举办。

软件

ContextCapture 自动从 AEROmetrex 拍摄的高分辨率图像中提取出最细致的细节,并据此生成费城的精确三维实景网格模型。ESM 将该网格导入 MicroStation 中,以添加临时结构的精确测绘数据、预测潜在问题,并与所有利益相关方进行协调。该解决方案还使用 LumenRT 增强三维模型,通过添加走动的人群、交通和动态阳光来模拟活动期间的各项条件。Bentley 软件的摄影测量功能和互操作性使协作得到了改善,并使规划和工程设计得到了优化。
Outcome/Facts
  • The extensive use of the visually realistic and dimensionally accurate 3D model by all stakeholders accelerated collaboration, enhanced decision making, and reduced risk.
  • Using ContextCapture in combination with MicroStation and LumenRT provided the modeling and simulation techniques to accommodate 56,400 temporary structures, 33 miles of security barricades, and special security requirements amid a busy urban infrastructure on a very tight timeline.
  • AEROmetrex used Bentley ContextCapture to automatically generate a high-resolution 3D reality model of Philadelphia from 28,000 digital photographs to help ESM plan and engineer the successful execution of the 2015 Papal Visit.
  • A model was built of the interior of the Cathedral Basilica of Saints Peter and Paul created from digital photographs taken with a simple, hand-held camera.
Quote:
  • “Bentley’s ContextCapture is an amazing piece of software. We were able to capture a detailed square mile of aerial photos supplemented by ground-based photography and automatically use them to produce a detailed 3D model of downtown Philadelphia.”

    David Byrne Technical Director AEROmetrex
  • “The fact that we test drove it [ContextCapture] on a 60-acre site, just gives us all the confidence in the world that the next arena, opera house, convention center or 60-acre site that we choose to employ this tool will be successful again and again, and this will be a tool that we use many, many times in the future.”
