GEOG 4354 Lecture Notes - Lecture 13: Stereopsis
Document Summary
Introduction to remote sensing lab october 28, 2016. Where one picture is taken to half (at least 60%) way overlap the other picture. The center of the first photo appears in the second photo, but it is no longer the nadir. Provides a map-like image to identify photographs that cover specific regions. Individual photographs are portrayed in their approximate geographic positions. Identifies each image by date, project, and often, the organization that acquired the photography. Our eyes are offset by a few inches a distance known as the interpupilary distance. Each eye provides an independent view of each scene the difference between the two views is known as stereoscopic parallax. Amount of stereoscopic parallax varies with distance closer objects exhibit more parallax than do distant objects. Our visual system can process the varying amounts of parallax in each scene to create stereoscopic views. For aerial photography, photographs are taken in sequence to represent each area in two independent views.
