ArcGIS Drone2Map 2024.1 - Support de la caméra thermique DJI

MarkBarker1

Avec la sortie de la version 2024.1, ArcGIS Drone2Map dispose désormais de capacités supplémentaires pour certaines caméras thermiques DJI très demandées. Un nouveau package d'installation optionnel de support pour caméra thermique DJI peut être installé en parallèle de Drone2Map. Il est disponible sur My Esri au même emplacement que les fichiers d'installation principaux. Ce package n'est pas nécessaire pour le traitement True Ortho, mais son installation permet à Drone2Map de reconnaître correctement les images provenant des capteurs DJI spécifiques lors de la création de nouveaux projets et permet à Drone2Map de rapporter les valeurs des pixels en unités de température dans l'orthomosaïque thermique True Ortho.<\/P>

Good news, thanks! I also noticed this is available for ArcGIS Pro 3.3 as well. Question - we use both Drone2Map and Site Scan Manager for processing our drone imagery - does Site Scan Manager also include this same DJI thermal camera support, or is this support unique only to Drone2Map 2024.1+ and ArcGIS Pro 3.3+ amongst Esri apps? Thanks for any insight.

@Will, yes, the ability to use the radiometric data in DJI's proprietary thermal image format is currently only available in the desktop offerings of our ArcGIS Reality product family, but not on the cloud with Site Scan. Some organizations cannot use the DJI Thermal SDK for legal or security reasons, which is why we offer it as an optional installation on desktop.

Thanks for the additional info. For more context, we have some Mavic 2 Enterprise drones with thermal, but I don't believe they are the later-released "Advanced" model, and we also have some older Zenmuse XT thermal cameras we've adapted to use with a Matrice 210 and/or Inspire 1v2 drones - if we wanted to create thermal (true radiometric/temperature) orthos from these cameras, we would be able to do so in Esri products, if so, which apps? Is it just that with the newer DJI models listed above they've gone to a newer proprietary format which requires the add-in compatibility installer, but thermal imagery from older DJI drones can still be processed without that add-in? Thanks.

Hi @Will,

You can process the older model DJI thermal drone imagery without the SDK. You are correct in that the newer models are the drones that require the additional SDK install to process properly. I can’t say for certain, but I suspect this will be the case going forward with DJI thermal drones. As for which Esri software can process the older model DJI thermal imagery, we have ArcGIS Drone2Map, Site Scan for ArcGIS and Orthomapping in ArcGIS Pro. All three should support the processing of thermal imagery from the older DJI sensors. If there is a camera model that you find is not working for some reason, then please let us know and we can investigate.

Regards,

Mark

@MarkBarker1 we're trying to extract temperature data from a thermal true ortho in Arc Pro. Our drone is Mavic 3T, processed in the latest version of Drone2map with the DJI camera support downloaded as well. What am I missing here? I don't see a way to convert pixel data to temp.

Any help would be much appreciated.

Hi @BrentDoty,

The M3T camera didn't get fully added to the digital cameras file we use to populate the camera information. We have fixed it in our patch coming this next month, but for now you can try to edit the file yourself to get it recognized. Just keep in mind this is a try at your own risk, so I would recommend creating the backup of the file. Steps would be as follows:

Make a backup copy of DigitalCameras.dat (C:\Program Files\ArcGIS\Drone2Map\bin\DigitalCameras.dat)
Copy the DigitalCameras.dat to another directory
Open it with a text editor
Find the M3M RGB camera
Add the entry below that camera and make sure it looks like the screenshot
Save the changes
Copy the edited DigitalCameras.dat into C:\Program Files\ArcGIS\Drone2Map\bin

Let me know if you are still having trouble if you attempt the above steps and we can discuss it further over a call or through email.

Regards,

Mark

@MarkBarker1 thanks for the update and workaround. We will try to implement it this week.

@MarkBarker1 joining in here a couple of months later 🙂 A client ask if Drone2Map support for DJI thermal H30T (or is it ZH30T - https://enterprise.dji.com/zenmuse-h30-series/specs) Same "trick" with the DigitalCameras.dat file will do it? Thanks! best pH
