Hi, we are trying to generate a big reflectance map. We have already done steps 1 and 2. Now, we are trying to get the reflectance maps, but the software crashes. Here is the output register:

Do you have any clues what could be happening? Is there anyway to send it to process in the cloud including 2D geografical MTPs corrections?
Can you tell me which version of the software you are using? Could you please download the latest preview of the software from https://cloud.pix4d.com/download/ and try to process your project using this version?
If that does not work, could you share the dataset with me so I could test it from my side (you can also open a ticket)? The easiest would be if you could upload it to cloud directly from the desktop so I would use the same processing options as you. To upload it to the cloud please see the instructions given in this link: https://support.pix4d.com/hc/en-us/articles/202558589-How-to-upload-project-files-from-the-desktop. You can share the link with me once you have uploaded.
I’ve been experiencing exactly the same problem as Jose. When Mapper goes to create reflectance maps in the third block of the processing it gets bugged. Unfortunately, I see there was no more info or resolution to this problem in this post. In my case, Mapper went crazy, it was still running for more than 12 hours after starting to process -my laptop kind of hijacked- and Mapper never ended. I had to stop it “using the force”.
The message I get in the log is the same:
[Warning]: Load ortho: skip image \<DSC00412\_geotag.jpg\>: image is not calibrated
I got it for all the 265 RGB pictures of my dataset.
I guess I am using last version of Mapper (v4.3.31) as I installed it last week.
Are you using RGB images or multispectral? In both cases, if you use the ag template, it uses alternative calibration (which is optimized for vegetation). However, the pipeline is based on the assumption that the images are nadir. If not, the images will not calibrate.
The way you will understand if this is happening:
Open your log file and search the word oblique (ctrl+F)
If you find the word oblique, process with standard calibration method.
I am facing the same issue of calibration with NIR images. Did your problem get resolved, if yes, then what was the problem and how you solved it?
Also, a set of images that were orthomosaiced with the previous pix4D version could not be orthomosaiced with the updated version. Is the new version causing issues?
We have looked at your quality report and replied to your support ticket. We looked at your images in QGIS and it seems it is a modified camera with 3 bands (not only NIR but NIR, Red and green). So you need to use ag modified template and select TetracamADC_8.4_2048*1536 camera model from Image properties editor. Also, use all prior in internal parameters optimization. Multispectral cameras have separate sensors and one image for each band. However, modified cameras are composite images where the images of each band overlay each other.
Hi, i have problem generate reflectance map too. I have already done steps 1 and 2. Now, i have a problem in step 3 that
“generate reflectance map (green) failed!”
Can i get the solution please?
Can you please share with us your quality report and the log file of the project? You can create a ticket to support directly or share it here (if you share it here more people will see your log file). This can happen because of a RAM issue, but we can check that with the log file. Can you please let us know your available RAM as well? Please also open the log file and search for the word “available” you will see the available RAM at the moment of generating the reflectance map.
My primary purpose is to create an image to help with drafting and contour data. I get through the ortho image step but can’t seem to get past the Reflectance map step. I’ll probably have to cancel out just because it uses up too many resources. Do I need it? What is is used for or do I need it? if not, can I not process it. It took about a half an hour to get step three to the contour stage but the reflectance map has been running for around 4 hours so far. I have 32G if ram, 8 cores at 3.6ghz and an Nvidia Quadro RTX 4000 graphics card. Any thoughts
Thanks!!
Hi, You do not need reflectance maps. You would need reflectance maps if you are using maps for agricultural applications and that too, users mostly use it for multispectral images. You can disable the reflectance map generation. It is a RAM issue as more than 95% RAM is being used:
I have also experienced a big issue. When it comes to step 3 for generating a big reflectance map of the surveyed farm field under the Ag Multispectral template using Pix4D Mapper 4.9.0., an error message shows that “[Warning]: Failed to write Exif!” Please find the log file of the project for your kind advice.
