3D Urban UAV Relay Placement: Linear Complexity Algorithm and Analysis

3D Classification of Urban Features Based on Integration of Structural and Spectral Information from UAV Imagery

Three-dimensional classification of urban features is one of the important tools for urban management and the basis of many analyzes in photogrammetry and remote sensing. Therefore, it is applied in many applications such as planning, urban management and disaster management. In this study, dense point clouds extracted from dense image matching is applied for classification in urban areas. Appl...

Computational Complexity of Relay Placement in Sensor Networks

Route Planning for Relay Uav

To expand the operative area for surveillance UAV, we propose the use of a relay UAV. The relay UAV is used as an intermediary node in a communication network: the surveillance UAV transmits data to the relay UAV, which sends it back to a ground station. In this exploratory report, we calculate the route for a relay UAV, to ensure communication at certain time points, given the route of the sur...

proposing a novel algorithm for fault-tolerant relay node placement in wireless sensor networks

wireless sensor networks are composed of hundreds or thousands of small nodes called sensor that work together and are associated with a specific task or tasks to do. each of these nodes includes sensor, processor, communication components, a small memory and a source of energy. it is expected that wireless sensor networks will be used widely in many applications in near future. scalability and...

Rectification Algorithm for Linear Pushbroom Image of UAV

SUMMARY This research presents a method of rectification for the image flow acquired by UAV. The sensor on the UAV is a multi-channel push broom sensor. The linear array can cover a stripe with approximately 6 Km on the ground. The motions (roll, pitch, yaw, etc) of the UVA platform are influenced by the relatively low-altitude flying so that have the attitude changed which are terrible to prod...
