Input keypoints are empty

[LeeKum_Cheong]

Hi,

I am trying to use a rapid template and when processing the error failed with the following message:

"Processing Failed:

Exception found trying to select keypoints: Input keypoints are empty"

What could be the issue here?

The data used are from the Sample Asphalt 2D project.

Thanks in advance

I get the same error with the Sample Asphalt data.The four images at top left are the ones that are said to be empty. So from the full imagery set, I added in the next four images in line above these four. Got the same error but this time on the newly added images. This happens on my Windows 10 machine. I used the same data on a Windows 8.1 machine and got no errors.Drone2Map for ArcGIS​
