Aerial Observation for Marine Traffic Analysis

Automated Traffic Analysis in Aerial Images

In this work an automated traffic analysis in aerial image sequences recorded by an unmanned aerial vehicle (UAV) has been developed, which provides the trajectories of the vehicles especially during overtaking. Methods of photogrammetry and image processing are used to detect the vehicles and to determine and track their positions. Camera calibration is necessary in order to transform image co...

An Architecture for Intelligent Management of Aerial Observation Missions

Apex, an elaboration of the three-tier type architecture used successfully in many autonomy applications, is designed around the concept of modular reasoning and control services (RCSs) with response-time characteristics as a primary factor in module delineation. We believe this approach reflects a valuable synthesis of requirements from diverse missions types and systems, and avoids pitfalls c...

Behavioral Analysis of Traffic Flow for an Effective Network Traffic Identification

Fast and accurate network traffic identification is becoming essential for network management, high quality of service control and early detection of network traffic abnormalities. Techniques based on statistical features of packet flows have recently become popular for network classification due to the limitations of traditional port and payload based methods. In this paper, we propose a metho...

Combining Unmanned Aerial Systems and Sensor Networks for Earth Observation

The combination of remote sensing and sensor network technologies can provide unprecedented earth observation capabilities, and has attracted high R&D interest in recent years. However, the procedures and tools used for deployment, geo-referenciation and collection of logged measurements in the case of traditional environmental monitoring stations are not suitable when dealing with hundreds or ...
