Approach for automatic relative orientation,

摘要

Abstract: An approach is described for automatic relative orientation of a stereo pair of digital aerial images. Feature-based and area-based image-matching techniques are combined to automate the procedure of determination of conjugate points in the images. A coarse-to-fine strategy (image pyramids) and robust estimation techniques are incorporated into the approach. It was developed as one of the automation- oriented software components of a digital photogrammetric workstation. Results obtained from practical examples are presented and evaluated. !13
