High-precision digital sensor metrology for infrastructure modelling and mapping

这项研究提案的主要目标是开发一种多传感器系统，帮助精确绘制基础设施地图，以供其开发和管理。据估计，未来20年将向全球基础设施项目注入25万亿至30万亿美元(《金融邮报》，2009年1月26日)。仅在加拿大，2009/10年度的承诺额就已达120亿美元，国内总成本最终被认为是数千亿美元。与交通项目相关的成本占基础设施总成本的很大一部分。确定的任务之一是创建地理参考基础设施清单，记录每项市政资产的位置、状况和估计重置价值。二是基础设施建设项目，特别是地下建筑项目的劳动者安全问题。如果市政当局没有关于地下基础设施的位置和状况的准确记录，公共和工人安全就会受到威胁。不幸的是，这一方面被很好地记录下来，结果是悲惨的。北卡罗来纳州立大学的一份报告称，(全球)每天有一人死于地下公用设施被刺穿。这种悲剧在世界各地的几个国家都有很多例子。

The primary objective of this research proposal is to develop a multi-sensor system that assists in the precise mapping of infrastructure for its development and management. It has been estimated that between $25-trillion and $30-trillion will be injected into global infrastructure projects over the coming two decades (Financial Post, 26 January 2009). In Canada alone, there is already a commitment of $12 billion for 2009/10 and the total domestic price tag is eventually deemed to be several hundred billion dollars. Costs associated with transportation projects account for a significant portion of the overall infrastructure costs. One of the identified tasks is the creation of a georeferenced infrastructure inventory recording the location, condition, and estimated replacement value of each municipal asset. The second is the worker safety on infrastructure construction projects, specifically sub-surface construction projects. Public and worker safety is jeopardized when municipalities do not have an accurate record of the location and condition of subsurface infrastructure. Unfortunately, this aspect is well documented with tragic results. A report from North Carolina State University states that there is one death per day (globally) due to punctured sub-surface utilities. There have been many examples of these tragedies in several countries around the world.
