if anyone comes across this; I didn’t solve this yet; I thought it may be because my images are grayscale. I found this example from Minnesota used ODM to stitch together historical aerial imagery. I examined the source images and they were grayscale but they were in the RGB colorspace, so I thought, maybe I should covert my images to the SRGB colorspace.
so I tried that using imagemagick (same version as before; convert is one tool within the imagemagick suite): for i in ls *.tif; do convert $i -colorspace sRGB $i.jpeg; done; which should have converted them to the RGB colorspace, but I used identify again, the photos’ colorspace was still reported as gray in imagemagick. I had the same results again too when uploading them through cloudodm.
I’m deciding to try this again in the native odm client to see if I can obtain more verbose results.
(Update: I decided to use the odm client instead, and my findings are at Unable to convert scaled value (1e+32) to int32 (PDAL) (with grayscale colorspace images)
