Colour Aerial Photography for Riverbed Classification
Colour aerial photography has the potential to identify and classify the size characteristics of exposed riverbed sediments over large areas efficiently. This paper describes the findings of a pilot project that sought to assess this potential and consider the impact of photo-scale on the accuracy of classifications obtained. Colour multi-scale digital imagery was acquired of a test area (120 x...
متن کاملCCD Requirements for Digital Photography
Digital photography has the potential to supersede conventional film photography. In order to realize this potential, digital photography needs to provide the best image quality and highest utility. We have used our modeling of photographic systems and our experimental measurements of CCDs in order to estimate the photographic potential of specific CCDs. We have also extrapolated the future req...
متن کاملAutomated Georeferencing of Historic Aerial Photography
Historic aerial photos are typically very popular, sought-after collections in library archives. Their ability to be used in GIS is limited, however, by the laborious and painstaking georeferencing process. A method is presented for automating the georeferencing of historic aerial photography. In this method, the Harris Corner Detector is used to detect corner points in already-georeferenced an...
متن کاملAerial Photography using a Nokia N95
A low cost UAV for aerial photography is constructed and tested. The UAV transfers images as they are captured via 802.11g to a ground station. Photo-mosaics are immediately assembled using SIFT keypoints for automatic image registration.
متن کامل3-d Terrain Reconstruction with Aerial Photography
This paper presents the 3-D terrain reconstruction with aerial photography. The results of 3-D reconstruction using intensity-based matching and hybrid intensity-based and epipolar geometry approach matching are shown and compared. The intensity-based image matching uses maximum normalized cross correlation to find the displacement vector between two images. This method can overcome the effect ...
