Thermal Performance Detection Method of Building Envelope Structure Based on UAV Infrared Thermal Imaging

Abstract

The invention relates to an unmanned aerial vehicle infrared thermal imaging-based thermal performance detection method for a building envelope structure. The method comprises determination of a path,photographing of an infrared thermogram, acquisition of information of space coordinates, temperature range division, image stitching, data weight calculation, human-machine interaction, analysis, evaluation and the like. According to the method provided by the invention, an original infrared thermogram is divided into temperature range images, so that detection personnel can observe a temperature difference more intuitively; aerial photography of an unmanned aerial vehicle and a virtual reality technology are combined, so that the detection and evaluation method is more intelligent, humanized and intuitive, and a detection result is more accurate.

Description

Technical field [0001] The present invention relates to a detection method, and more particularly to a thermal performance detection method of building envelope structures based on drone infrared thermal imaging. Background technique [0002] As people's living standards are gradually improved, the proportion of building energy consumption accounted for total building energy consumption is gradually improved, and the key to solving building energy consumption is the building energy saving. Therefore, in recent years, the evaluation criteria for building enclosure structures such as green buildings or energy-saving buildings have been introduced, and new energy-saving buildings based on building energy saving concepts have been widely promoted. Although the building design phase is designed according to the energy-saving standards, the construction stage is due to the impact of various field environments, and the various links to build buildings are not fully integrated. The therm...

Problems solved by technology

[0004] At present, the laboratories of various institutions have matured the thermal performance testing technology of building components such as doors, windows and walls. In the detection method of the overall thermal insulation performance of the structure, the detection instrument is simple, the measurement result is not convincing, and the test method is very subjective and restrictive; the invention patent of publication number CN 102636313A discloses a leak based on infrared thermal imaging image processing In the source detection device, the test conditions are strict, time-consuming and laborious, and the process is cumbersome; the invention patent publication number CN103196565A discloses the method for marking indoor energy-saving detection points in buildings based on infrared heat maps, which introduces the analysis of indoor infrared temperature interval images in buildings, but still No specific method for infrared thermal image detection of the whole building is proposed

[0005] At present, in the field of infrared thermal imaging detection of buildings, there is no complete testing and evaluation method or system for the thermal performance of building envelopes that can be applied in practice.
