Pix4Dmapper project stopped at the beginning of step 2

PIX4Dmapper PIX4Dmapper Questions/Troubleshooting
1

I am using the Pix4Dmapper software for my UAV remote sensing image analysis. A 3-band multi-spectral camera was used. Also, GCPs were automatically detected by Pix4Dtagger.

Most of the projects finished with satisfying results, but some of them stopped with unexpected errors at the beginning of step 2. Could you teach me what should I do to solve the problem?

I am attaching the xml file of the project report (the log file cannot be uploaded perhaps due to its large size).
report.xml (559.0 KB)

The following is a part of the log file where the fatal error occurred:

Hi, you can upload the logfile here: 101612 - Google Drive. We would also need the pdf quality report. You can generate it from the menu: https://support.pix4d.com/hc/en-us/articles/202558319-Menu-Process-Generate-Quality-Report

Hello, thank you for your response. I have uploaded the log file and the pdf quality report. Could you check them?

Hi,

I can see that this is a multispectral camera we do not have in our database. The multispectral cameras in our database exist as a rig (https://support.pix4d.com/hc/en-us/articles/115005852003-Processing-camera-rigs). One band (by default green as green band images have the most variability) is used to calibrate the other band images. In your case, the images are being processed as different cameras and thus Pix4D is not able to calibrate the images from the bands with low variability.

You will need to process this camera as a rig. If the cameras in the sensor are far apart, you need to know the translation x, y,z values. If the images are already aligned, you will need to input these values as 0 (translation x, y, z). I have enabled the rig add-on for all your licenses. You will need to log out and log in again to find the option. the workflow will be similar to this: https://support.micasense.com/hc/en-us/articles/360049894753
