Good Day Trust you are well, Could you please assist, we need assistance with Pix4D Mapper. 1. We recently purchased a DJI P4 Multispectral drone for agricultural purposes. We have since not been able to successfully process any of our projects. We continuously receive errors stating “Camera Calibration”, Could you please assist us in rectifying the error? 2. Do you perhaps have a reflectance image for us or where would we be able to get it? Your quick response will be highly appreciated. Thanking you in advance. Kindest Regards, ---
