Thermal Infrared Orthophoto Geometry Correction Using RGB Orthophoto for Unmanned Aerial Vehicle

open access: yesAerospace
The geometric correction of thermal infrared (TIR) orthophotos generated by unmanned aerial vehicles (UAVs) presents significant challenges due to low resolution and the difficulty of identifying ground control points (GCPs). This study addresses the limitations of real-time kinematic (RTK) UAV data acquisition, such as network instability and the ...

Extracting building heights from lidar data for the purpose of creating true orthphoto [PDF]

open access: yes, 2012
Classical orthophoto has some disadvantages, which are eliminated in the process of generating true orthophoto. True orthophoto is generated from aerial photographs and digital surface model (DSM) in a process of enhanced orthorectification.

Digital Orthophoto Generation with Aerial Photographs

open access: yesAcademic Journal of Interdisciplinary Studies, 2014
Orthophoto process transforms a vertical aerial photograph in to the equivalent of traditional map. Yet it retains the advantages of a photograph-virtually displaying actual cultural and land features and the built environment rather than representing those features using symbols and lines. With the development of technology, Digital photogrammetry has

Analytic Inspection on Large Scale Orthophotos

open access: yesJournal of the Japan society of photogrammetry and remote sensing, 2008
Recently orthophoto has been spreading in public, as the rectifying processes become easier under the development of digital photogrammetric workstation. Though it might be seemed familiar for public as the images are just like real, but some professional knowledge of photogrammetry are required to make interpretation relevant.This paper discusses ...

Visualizing the Geology of Lake Trout Spawning Sites: Northern Lake Michigan [PDF]

open access: yes, 2004
Geologists and biologists are working together to understand the links between lake floor geology (composition and shape) and the distribution of lake trout throughout their life cycle. Lake floor geology is one of the main factors determining where lake

Algorithm for image-based architectural element recognition [PDF]

open access: yesFME Transactions, 2019
This research describes an image-based algorithm for a shape recognition of an architectural element from an image. Given an orthophoto of a particular element such as a window, and a query image of the object facade, the algorithm estimates the level of
