Abstract

The invention relates to an urban drainage pipeline acceptance method for pipeline mapping based on machine vision. A machine vision imaging detection system collects surrounding environment signals of a complex pipeline, then transmits the image data of a deep drainage pipeline in real time, and performs 3D scene construction according to the image data to generate a 3D augmented reality fusion image. A GIS positioning information query analysis system can perform positioning roaming, and leave an acceptance track in a map layer to generate a mapping drawing. A central control command systemis connected to the machine vision imaging detection system and the GIS positioning information query analysis system, and is used for remotely managing the acceptance of a pipeline mapping instrumentand the drainage pipeline, calculating and judging the condition of the drainage pipeline in real time according to the image data, the environment data, and the 3D fusion image, and releasing a mapping acceptance report. The urban drainage pipeline acceptance method based on the machine vision pipeline mapping can solve various problems such as dangerous and complex environment, complex lightingconditions, difficulty in reaching the pipeline by hand, and the limitation of real-time command during the pipeline mapping and the pipeline engineering acceptance.

Description

technical field [0001] The invention relates to the technical field of pipeline safety monitoring, in particular to a method for checking and accepting urban drainage pipelines based on machine vision pipeline surveying and mapping. Background technique [0002] The construction of modern digital pipe gallery is an important part of digital city construction. During the construction, use and maintenance of underground pipes, it is necessary to measure and map the internal conditions of the pipes. Traditional manual methods are inefficient, low in safety, and cannot be objective , quantification, and visualization. [0003] With the increasing maturity of signal processing technology, machine vision technology, artificial intelligence technology, and positioning and navigation technology, robots are used to replace humans to achieve accurate and accurate surveying and mapping in harsh environments, and to achieve a high degree of automation. Intelligent operation has become t...
