Background Along with the intelligent upgrading of urban underground infrastructure, the scale and complexity of underground pipelines such as electric power, communication and the like are continuously improved. The cable channel is used as a key infrastructure for bearing various pipelines, and the accurate acquisition of spatial information of the cable channel has important significance for realizing scientific management of pipeline assets. At present, data acquisition of a cable channel mainly depends on arrangement of measurement datum points at a cable well, and space coordinates of key nodes of the channel are acquired through mapping equipment. The acquisition method based on the fixed nodes can acquire the basic spatial information of the cable passage, and is widely applied to general survey of underground pipelines. However, as the density of underground pipelines is increased, the space inside the cable passage is increasingly more compact. In practical application, the acquisition method based on the fixed node is difficult to accurately acquire the actual track and buried depth data of the cable section, and the integrity and consistency of the acquired data are difficult to ensure. Particularly, when the cable position deviates from the design position, the lack of effective space positioning and deviation analysis mechanisms easily causes that the acquired data is inconsistent with the actual situation, thereby reducing the accuracy of data acquisition of the cable channel.
