The Design of Lenses for Aerial Photography

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

Investigation of Fisheye Lenses for Small UAV Aerial Photography Masters by Research in Electrical Engineering

Aerial photography obtained by UAVs (Unmanned Aerial Vehicles) is an emerging market for civil applications. Small UAVs are believed to close gaps in niche markets, such as acquiring airborne image data for remote sensing purposes. Small UAVs will be able to y at low altitudes, in dangerous environments and over long periods of time. However, the small lightweight constructions of these UAVs le...

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...
