High-precision digital sensor metrology for infrastructure modelling and mapping

本研究计划的主要目标是开发一种多传感器系统，以协助基础设施的开发和管理的精确测绘。据估计，在未来二十年，全球基础设施项目将投入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年度就已经有120亿美元的承诺，而国内的总费用最终将达到数千亿美元。与交通项目相关的成本占总体基础设施成本的很大一部分。其中一项确定的任务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，特别是地下施工项目的工人安全问题。如果市政当局没有准确记录地下基础设施的位置和状况，就会危及公众和工人的安全。不幸的是，这方面的记录很好，导致了悲剧性的结果。北卡罗来纳州立大学的一份报告指出，由于地下公用设施被刺破，每天（全球）有一人死亡。在世界上许多国家都发生过这样的悲剧。

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.
