I have collected geo-referenced drone data along with some SONY DSLR ground photos for a Proof of Concept job on an interchange. I have been trying to use the ground photos to improve the billboard signs along the interchange which have 'holes' in them after initial processing of the model. One of the posts in the communities on merging models, mentions obtaining co-ordinate values from the tie-points editor and importing it as a GCP into the ground photos to correct the AT for the Ground Photos. I have not very familiar with using GCP's in ContextCapture and followed the necessary steps as follows: (See: https://communities.bentley.com/products/3d_imaging_and_point_cloud_software/w/wiki/26852/merging-models ) Process a “standard” AT on the high-res (ground) dataset On this Aerotriangulated block, open the Tie-points editor Identify points of interest that can also be viewed in the “10cm” (aerial) model and click them in at least two photos to get their estimated coordinates. Save this values in a GCP import file. Open the 10cm Aerotriangulated block Open the ControlPoints editor Add the freshly identified points and their coordinates in the GCP tab Point them in some “10cm” images and save Run an AT on the “10cm” block using these GCP for adjustment Your two blocks (high-res and “10cm”) are now correctly georeferenced and ready for merging step When I run AT on the Ground Photos with the GCP coordinates imported from the drone data, I do not have the option to select Use Control Points for Adjustment in the AT settings (It is grayed out and Control Points must be provided in Block Definition appears in yellow.. Can someone walk me through the process or point out what I may be doing wrong? Thanks!
