Good morning, I am contacting the community because I am encountering an error message when attempting to mosaic the multispectral images taken using the M3M camera on the DJI Mavic3 M drone. The error message is “Error e0046: Processing failed. No calibrated cameras.” This error does not occur when creating the RGB mosaic. Please let me know if you have encountered a similar issue or have any suggestions on how to resolve it. Thank you in advance for your assistance. Best regards, [Name] The images in question refer to two flights in the same location, but which were made on different dates. However, in the interval between one date and another, two flights were made in different locations, and when the mosaics were made, they did not show the same error. This leads me to believe that the problem is not with the drone or the camera, but with the software. I would therefore be grateful if anyone could share their experience of this problem and the solution they found. Thank you in advance for your assistance. ---

I’m also facing the similar problem while processing DJI M3M imagery in pix4D mapper. ---

@pix4d9 Error e0046 is mainly related to the image quality, low overlap and lower flight height. If you are having issue with M3M, then make sure you have 80% front and side overlap, and flight height of 40 meters or higher. What is your flight overlap, and the flight height for image acquisition ?
