摘要地下管线的开挖破坏是一个严重而普遍的问题。据估计，美国每年有近50万起公用事业罢工。进一步的分析表明，这个数字相当于每分钟一个公用事业罢工。这种公用事业线路罢工导致伤亡、昂贵的服务中断、罚款和处罚以及沉重的维修费用。从2001年到2010年的十年间，共发生了544起与挖掘有关的重大事故，造成37人死亡，152人受伤，财产损失近2亿美元。挖掘机操作员面临的两个关键问题是，缺乏准确的位置和语义数据，加上缺乏持久的视觉指导。安全挖掘操作的第三个障碍是缺乏挖掘工具与底层邻近设施的接近度的实时空间感知。为了缓解这个问题，作者提出了一个实时的可视化仿真框架。
AbstractExcavation related damage to underground utility lines is a serious and widespread problem. It is estimated that there are close to 500,000 utility strikes in the United States every year. Further analysis reveals that this number equates to one utility struck every minute. Such utility line strikes lead to fatalities and injuries, costly service disruptions, fines and penalties, and heavy repair costs. The decade from 2001–2010 saw a total of 544 major excavation related accidents resulting in 37 fatalities, 152 injuries, and close to $200 million in property damage. Lack of accurate position and semantic data of buried utilities coupled with absence of persistent visual guidance are two key problems facing excavator operators. The third obstacle to safe excavation operations is the lack of real-time spatial awareness of the proximity of the digging implement to the underlying neighborhood utilities. In an attempt to alleviate this problem, the authors propose a real-time visual emulation framewo...
