I have calibrated images abutting uncalibrated images. When I try to add a MTP the only the uncalibrated images appear. How do I get the calibrated images to appear so I can add MTPs to both sets of images?
Would you please follow the steps described in
How to add / import and mark manual tie points (MTPs) in the rayCloud? If the issue persists, I would appreciate if you could send us a screenshot to have a better understanding of the error.
But what happens when the uncalibrated images only show tie points on the images that aren’t even close to the actual tie point location?
Even when I add manual tie points, the calibrate button is still greyed out.
If I understand your question correctly, usually, you can correct the location by marking the right place on the images. I am not sure which “calibrate button” on Pix4Dmapper. Would you please upload the screenshot of it?
