FLIR cameras or other thermal imaging systems can provide visuals and insights from subsurface in concrete bridges where delimnations and spalls are hiddent as an innovative solution replacing old fashion chain dragging. a dual RGB+Thermal images , RGB for mesh production, layered with thermal needing a calibration and boresighting between two sensors. also heat islands for aerial photography
Hello,
When the input images are R-JPEG thermal images, it is possible to produce a temperature map alongside the RGB
orthomosaic. This temperature map uses the radiometric data embedded in the R-JPEG image's metadata as an input, and it can represent the temperature data in Celsius, Kelvin or Fahrenheit degrees.
The temperature map orthomosaic can be visualized in third-party software such as QGIS, or ArcGIS Pro.
Note: This feature is only possible when using radiometric thermal cameras. A radiometric thermal camera holds
an actual temperature value for every pixel in the captured image, whereas a non-radiometric sensor only contains a
visual representation of the measured value of radiation at the time the image was captured, and no other data.
