Orthorectification in IMAGINE without a camera report

Question

Is a camera calibration report required for Orthorectification in IMAGINE?

Answer

 

For IMAGINE

Orthorectification is possible without a camera calibration report with the Direct Linear Transform model but ground control points are required. It is appropriate for use with single perspective imagery such as aerial photography.

 

The Direct Linear Transform model is available from Transform & Orhtocorrect > Control Points. This 3D model requires that GCPs provide 3D ground information (X, Y and Z) and are well-distributed horizontally and vertically.

 

For IMAGINE Photogrammetry

IMAGINE Photogrammetry will need camera parameters.
