Big Data in Urban Construction Archives and Urban Management: Detected Underground Pipes Alignment with Urban Construction Records
Cities are densely populated, with concentrated tall buildings and convenient transportation, reflecting their prosperity and developments. In urban construction archives, the records of underground pipe is very important for practical engineering. However, in real engineering sites, the buried pipes sometimes has the different layout from the records. Therefore, the survey is often carried out before excavation. In this paper, we present a method to align the detected pipe lines with existing records. In this method, the dynamic time warping (DTW) has been used for the alignment. In this way, the records and the detected records can be checked for consistency. The algorithm has been checked on several data sets to demonstrate the effectiveness.
