Building heating ventilation pipeline detection method based on thermal infrared imaging

Abstract

The present invention provides a building heating ventilation pipeline detection method based on thermal infrared imaging. The method comprises: performing itineration observation of the internal area, to be detected, of a building through adoption of a thermal infrared imager, and shooting the infrared images of the area to be detected; extracting the image features of the infrared images, combining the pipeline water body infrared image features to identify the distribution of heating ventilation pipelines, and determining whether normal supply at the areas where the heating ventilation pipelines are existed as known are performed or not; and performing fixed point infrared shooting of the fault high-incidence areas of the heating ventilation pipelines, performing processing of the shot infrared images, and confirming problems which are likely to be happened in the fault high-incidence areas. The building heating ventilation pipeline detection method based on the thermal infrared imaging is visual and rapid in detection, high in precision, can realize rapid and accurate detection and maintenance of the heating ventilation pipelines at the internal portion of the building.

Description

technical field [0001] The invention relates to the field of building pipeline detection, in particular to a building heating and ventilation pipeline detection method based on thermal infrared imaging. Background technique [0002] With the improvement of residents' living standards and the advancement of building technology in recent years, more and more people use building heating and ventilation pipes for heating. In particular, the popularity of floor heating makes it more difficult to maintain and overhaul building HVAC pipe networks. Once blockages, leakages, and other faults occur, it is difficult to quickly and effectively find the fault point. [0003] At present, there is a lack of scientific and strict testing and management methods for building HVAC pipe networks, making it difficult to check and repair. In the prior art, the maintenance of the pipe network inside the building is mostly carried out by manual visual inspection. The buried pipeline makes it impo...

AI Technical Summary

Problems solved by technology

The buried pipeline makes it impossible to carry out the manual visual inspection method, the detection is difficult, and the fault point cannot be accurately detected, resulting in the lack of daily maintenance of the pipeline

When a failure occurs, it is often necessary to dismantle the interior decoration of the building in a large area, and troubleshoot and troubleshoot section by section, causing a lot of waste and inconvenience
