Pix4Dmapper not converting RJPEG images to tiff from Zenmuse H20T and Mavic 2 dual enterprise advanced thermal camera

I am trying to process some images captured with the new H20T but upon import pix4d is not recognising them as RJPEGs and converting to tiff.

Images have been verified as proper RJPEGs in other software (thermal measurements possible)

Please help

Hi Ben, Are you sure the format is rjpeg? Can you check in the FLIR software? It also might be some DJI format. We have a FLIR SDK integrated with Pix4DMapper that converts the rjpg images to jpg.

Has this issue been resolved? I am also considering purchasing the H20T and use its outputs in Pix4D Mapper.

Unfortunately not, it appears DJI have encrypted their data and thus made the thermal data from the H20T practically useless unless you are happy using their abysmal thermal analysis tool. Its a joke!

Oh wow! Well, that’s good to know. Thanks for the reply Ben.

Hi Babak, the format is not the same as the other thermal images rjpeg format which is why Pix4D is not able to use the FLIR SDK for converson to tif and use them to produce thermal maps with temperature values.For H20T, you can only generate thermal maps for visualization.

Hi Momtanu. What you just said above its possible? I’ll be buying the M300 RTK with the Zenmuse H20T and I wanted to know if I can use the RGB and thermal images of the camera into pix4D and work with it.
For thermal i would want to do thermal orthomosaics (maybe not radiometric) but to see where I can find anomalies and detect them easily.

Thanks

Hi, you will need to process the RGB and thermal as different projects. For the thermal, you will get an RGB map (not a grayscale one with temperature values). You will still be able to use it for visualization and by looking at the colors on the map and the color scale, you will be able to detect anomalies but will not be able to get the temperature value of that particular object/pixel.

Thank you Momantu, can you show me an example of what you are talking made with an H20T. I will appreciate it a lot.

Thank you!

Thank you for the Email!

So basically, I would be able to make this type of map but not get the temperature of the pixels.
Am I right?

Exactly!

Hi all

I’ve been read some information about this topic (Thermal H20T+PIX4D Mapper) and, if I’m wrong please rectify me, and I do not have anything clear about that. I’d like to use PIX4D Mapper to process images from my H20T sensor, mainly working with photovoltaic installations, but I really don’t know if that is compatible. As you all must know, H20T is a singular camera (3 cameras in one), used only for DJI Matrice 300 TRK. Its thermal resolution is high, 640 x 512 and format RJPG. I’m not an expert yet but, as I’ve understood when I read, is not possible work with PIX4D plus Thermal H20T. Is that correct? Thank you. Note: I just know that thermal H20T sensor is not FLIR, like Zenmmuse XT2.

Good day

Kindly advise I’m looking to buying a mavic 2 dual enterprise advanced which has a sensor of 640*520 can this work on pix4d mapper when processing thermal images

Hello All,

As Momtanu said, the thermal image EXIF format is not the same as the other thermal images rjpeg format which is why Pix4Dmapper is not able to use the FLIR SDK for conversion to tiff and use them to produce thermal maps with temperature values. For Zenmuse H20T and Mavic 2 dual enterprise advanced, you can only generate thermal maps for visualization.

This means, for the thermal images, you can still process them as RGB images (not a grayscale one with temperature values). You can use it for visualization and by looking at the colors on the map and the color scale, you will be able to detect anomalies but will not be able to get the temperature value of that particular object/pixel.

Thank you Kapil
