Hi, I have a project in which I am using two gopro’s to reconstruct a section of beach. The automatic reconstruction did not calibrate most of the images and after adding 120 manual tie points I have all the images from one camera (apx220 images) calibrated however I am getting a triangulate error on a significant amount of my MTPs and some very large projection errors. I have ensured that my MTPs are correctly selected could you tell me what is causing the large projections errors and are my MTPs being considered in the generation of a point cloud? And if they arent being considered is there something I can do to have them considered? Thanks Anastasia ---
