Orthophoto and pointcloud generation without GCP

Question asked by Santiago Cuevas on Jun 12, 2019

Hello, I have enough experience in creating orthophotos and point clouds using the corresponding Ground Control Points (GCP) for the process, however in this case I want to create them without GCP, I heard is possible to do using a calibrated camera from another project. I have the camera parameters, the photos, the GNSS/IMU data (EXIF data), but NO Points (GCP) and I failed to create a satisfactory workflow. I am not sure about the correct settings at each stage (tie point extraction, orientation, surface generation and orthophoto).

Could someone give me some guidance or tips to achieve this?

Thank you. Best regards!
