The application of CCTV and QV pipeline network detection technology has been increased in survey and design projects such as rainwater and sewage diversion in cities, quality and efficiency improvement in standard areas, and renovation of waterlogging points. In addition to meeting the basic requirements of physical investigation, the detection results also requires labelling and statistics on the pipeline network defects, branch pipe sources, mixed flow characteristics and so on. Based on summarizing the practical experience of multiple important projects, this paper develops a set of system that integrates field data collection and pipeline network automatic mapping of pipeline networks, and introduces the application of data acquisition and mapping system based on drainage pipe network detection with examples.
