Problem with aerial dataset, curved model after AT. Poor accuracy with the final Orthophoto.https://communities.bentley.com/products/3d_imaging_and_point_cloud_software/f/contextcapture-descartes-pointools-forum/217723/problem-with-aerial-dataset-curved-model-after-at-poor-accuracy-with-the-final-orthophotoHi, I use Dji Phantom 4 RTK for mapping surveying. I have problem with aerial dataset, when i import photos of 1400 meters length road and start AT, it becomes curved.

Did you took photos with or without DJI camera distortion correction?</span></p> <p><span>How did you generate orthophoto from 2.5D or 3D production?</span></p> <p><span>Do you have any GCP to use as checkpoint for accuracy control?</span></p> <p>How did you calibrate camera?</p><div style="clear:both;"></div>RE: Problem with aerial dataset, curved model after AT.
