Abstract

An embodiment of the invention provides a method and a device for detecting buried depth accuracy of a pipeline, and relates to the technical field of data processing. The method includes: acquiring a field operation acquisition data set and a measurement result data set of the pipeline to be measured, wherein the field operation acquisition data set includes a plurality of actually measured depth record data, and the measurement result data set includes a plurality of preset depth record data; comparing the actually measured depth record data and the preset depth record data one by one to obtain a plurality of depth difference values; acquiring a plurality of to-be-calculated depth difference values that are not larger than a preset threshold; calculating a mean square difference of the to-be-calculated depth difference values, and judging the accuracy of the measurement result data set based on the mean square difference value. Thus the accuracy of the statistical result data of the pipeline depth is achieved to support the inspection on mathematical accuracy of the pipeline data.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a method and device for detecting the buried depth accuracy of pipelines. Background technique [0002] With the continuous improvement of people's awareness of the importance of underground pipelines in economic construction and daily life, underground pipeline detection has also been popularized, and has gradually become an important part of urban planning and engineering construction. Many different manufacturers and models have emerged on the market. underground pipeline detection equipment. But for the underground pipeline detection project, the main purpose is to achieve the detection results consistent with the actual plane position and actual buried depth of the pipeline. Only when the detection results are close to the true value and meet the accuracy requirements can the project quality be guaranteed. The buried depth data obtained in the existing metho...
