Hi Dmitry,

The new EXIF feature in build 877 works spectacularly well!

Thanks!

General / Reset ground control to "null"

« on: April 29, 2011, 03:07:45 AM »

Is it possible to reset ground control points to "null" once they have been set? In my case, I thought the photos had locations in the EXIF headers -- it turns out the photos did not have this info. The locations were set to 0.000, 0.000, 0.000. But this meant that the area of the entire pointcloud/photoset was reduced to a single point.  I cannot find a way of clearing that information (entering a null value ends up with 0.000 in each of the x,y,z boxes).

General / Matching photo with sparse point cloud after alignment

« on: April 28, 2011, 10:02:18 PM »

How does one efficiently figure out which photo resulted in areas of the sparse point cloud after the photos are aligned? In some cases, I can see photos that very poorly matched and created obvious anomalies.  I'd like to delete those photographs.  However, when the number of photos is large, this is not an easy task.  Any tips for doing this? Otherwise, one has to keep deleting until the point cloud changes (right?). It would be great to be able to click on a point on the point cloud and have the photo(s) from which it was derived turn a color.
