I a having an issue with how Pix4d selects images to use for the orthomosaque where there is cloud shadow in some of the images. I am using an “Airinov multispec4C” camera which Pix4D recognizes as known camera model. This camera can recorded four bands (Green,Red,Red-edge and NIR) and in good conditions has provided good results.
The issue we encountered is that although Pix4dD is stitching each band successfully, when there is cloud shadow in some of the images the location of the clouds between the stitched bands is different. The can have a dramatic impact on an NDVI. I have attached screen shots of the ‘Red’, ‘NIR’ and ‘NDVI’ from a test site where this was observed.
Is there a way in Pix4D to ensure that when the band for one image is used for the orthomosaque, the other bands from the same image will also be used in the same location in their corresponding orthomosaque? I also tried to submit this as a request but the site kept crashing.
Thank you for any help you can provide.
