AUTOMATED LOW-COST PHOTOGRAMMETRY FOR FLEXIBLE STRUCTURE MONITORING

Low Cost UAV-based Remote Sensing for Autonomous Wildlife Monitoring

In recent years, developments in unmanned aerial vehicles, lightweight on-board computers, and low-cost thermal imaging sensors offer a new opportunity for wildlife monitoring. In contrast with traditional methods now surveying endangered species to obtain population and location has become more cost-effective and least time-consuming. In this paper, a low-cost UAV-based remote sensing platform...

Automated Landslide Monitoring through a Low-Cost Stereo Vision System

In this paper we introduce an inexpensive yet efficient photogrammetry system that takes advantage of state of art computer vision techniques to monitor large natural environments. Specifically, our system provides a precise evaluation of the terrain flow in wide landslides through optical flow applied to 2D image sequences and a back-projection of the resulting motion gradients to a 3D model o...

Towards a New Paradigm for High-resolution Low-cost Photogrammetry

Current mobile primary data acquisition systems can be grouped in three main categories: terrestrial, manned airborne and satellite borne. This paper discusses whether Unmanned Aircraft Systems (UASs) together with the appropriate sensing and navigationorientation payloads can constitute a new, fourth data acquisition paradigm of the high-resolution and low-cost type. For this purpose, and base...

‘Structure-from-Motion’ photogrammetry: A low-cost, effective tool for geoscience applications

Potential Substrates for Low-Cost Flexible Supercapacitors

Over the past several years, there has been a growing interest in the application of supercapacitors as replacements for conventional batteries, which are significant contributors of heavy metals into the environment. Flexible supercapacitors, unlike the traditional rigid supercapacitor, can be constructed with more accessible and cheaper flexible substrates. I constructed carbon nanotube (CNT)...
