Estimation of Tree Positions from Aerial Photos
To estimate positions of individual trees in high– resolution aerial photographs we use circular templates derived from an optical tree crown model and the geometry at image acquisition. Local maxima are found for the correlation function for the successively transposed templates over the whole image. Using auxilliary information on the exact or approximate number of trees in the stand regarded...
متن کاملAnalysis of Costantino Landslide Dam Evolution (Southern Italy) by Means of Satellite Images, Aerial Photos, and Climate Data
Large landslides, triggered by earthquakes or heavy rainfall, often obstruct the river’s flow to form landslide dams, causing upstream inundations, and downstream flooding. In Italy, landslide dams are rather widespread along in Alps and Apennines: although the identification of past events is a complex task, some hundreds of landslide dams are identified in the literature. In order to assess t...
متن کاملRelief effects on aerial photos geometric correction
Aerial photos are the best support to detect changes in the landscape over the time, particularly when associated with GIS based analyses. Since all metrics calculated on a landscape (from area coverage by vegetation classes to patches shape and size) are sensible to geometric distortions, the geometric correction of aerial photos is due to allow a realistic multi-temporal study. In this paper ...
متن کاملMobile Manipulating Unmanned Aerial Vehicle (MM-UAV): Towards Aerial Manipulators
This paper presents a control scheme to achieve dynamic stability in an aerial vehicle with dual multi-degree of freedom manipulators. Arm movements assist with stability and recovery for ground robots, in particular humanoids and dynamically balancing vehicles. However, there is little work in aerial robotics where the manipulators themselves facilitate flight stability or the load mass is rep...
متن کاملUnmanned Aerial Vehicle (UAV) Cooperative Mission Planning
Unmanned Aerial Vehicle (UAV) is a kind of new operational platform possessing ability to flight autonomously and perform independently a task,which can not only carry out non-attack tasks,such as military reconnaissance, surveillance and search, but also to carry out tasks to air-to-ground attacking, target bombing and so on. With the rapid development of UAVtechnology, more and more UAV will ...
