It will be very useful that Itwin modeler could work with 4 bands imagery, and I mean Red, blue, green and near infrared images to produce true orthos. I refer to aerial camaras in general. It´s is a pity we can´t use these (4 bands) in orthoproduction. You talk about thermal imagery, but there´s another issue and it is very useful the software work with this ones as well, but this is not what we mentioned.
I work with the iXM-RS280F aerial camera, which captures RGB and N (near infrared) images. Can iTwin Capture process this additional non-thermal band and generate true orthophotos with all four bands (RGBN)?
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.
Hello,
Yes, I can share the dataset, but each image in GeoTIFF format with the 4 bands is 2.3 gigabytes. How would you like me to send you the data?
The camera is a PhaseOne iXM-RS280F
Thanks

Hello,
I wanted to know if it is necessary to update the software to take advantage of this new possibility of generating true orthoimages with the 4 bands?

Supported thermal cameras (list not exhaustive)
• Skydio VT300-Z and VT300-L
• Teledyne FLIR thermal cameras: C-series, E-series, T-series
• DJI M3T Enterprise Thermal
• DJI Zenmuse H20T and Zenmuse H20N
Can you check if the above applies to your datasets ? Can you let us know what camera are you using ?
