Problems solved by technology

[0009] (1) Low flexibility: Satellite and aerial remote sensing are limited to large-scale observations, and the matching degree and suitability for specific areas are not enough. It is impossible to obtain target anomaly information from large-scale data in a targeted manner, and it does not support Conditions and detection targets The custom remote sensing data observation mode can only be used as a reference in the early stage
[0010] (2) Insufficient data resolution: Satellite and aerial remote sensing observations have a large height, which makes it easier to obtain wider data coverage, but also limits the data resolution. As shown in Table 1, the waveband of the remote sensing infrared imaging system is 10 μm. The resolution is only 100m, which lacks the reflection of detailed information on surface thermal anomalies, and the interpretation results are prone to large deviations
[0011] (3) Lack of reflection on local geothermal anomalies: due to the low resolution of remote sensing data, satellite and aerial observation data do not reflect the finer details of local thermal anomalies, and local details are easily submerged in the regional background. remote sensing signal enhancement and extraction technology, the overall effect of this technology needs to be improved
[0012] (4) UAV thermal infrared imaging technology has not achieved good results in geothermal exploration applications: on the one hand, the current thermal infrared imaging technology based on UAV platforms is mostly used in public security, environmental pollution, precision agriculture, and power grid detection. There are few application practices in the field of geothermal exploration; on the other hand, in order to realize the rapid and precise detection of surface thermal anomalies, it is necessary to optimize and upgrade existing technologies and add functions such as real-time data return and preprocessing

Abstract

The invention provides a method and system for detecting thermal anomalies on the surface of an unmanned aerial vehicle equipped with infrared remote sensing. The method comprises: acquiring the real-time position of the drone; acquiring the real-time height of the drone; acquiring a thermal infrared image of the ground surface; acquiring a multispectral image of the ground surface; The spectral image is fused into a thermal infrared image map, and the surface temperature inversion module is used to invert the thermal infrared image map into a surface temperature distribution map, and the surface temperature distribution map is sent back to the control terminal. The ground surface thermal field detection method and system provided by the invention provided by the UAV equipped with infrared remote sensing can obtain data in real time at the control terminal, perform rapid preprocessing and ground temperature interpretation, compare the interpretation result with the actual measured temperature, and check the data quality in real time. Adjust the data observation plan in time for areas with poor interpretation effects, so as to realize efficient real-time detection of surface thermal anomalies.
