Building stone quarries: resource evaluation by block modelling and unmanned aerial photogrammetric surveys

An Evaluation on Different Number of Ground Control Points in Unmanned Aerial Vehicle Photogrammetric Block

This paper presents a novel method of unmanned aerial vehicle image processing using photogrammetric technique. The study area consist different slope class which involves undulating area around the Skudai area, Malaysia. All photogrammetric methods were applied in this study including selection of test area, flight planning, camera calibration and image processing orientation. A new ground con...

Review of Unmanned Aerial Systems (UAS) for Marine Surveys

Flight Dynamics Modelling and Experimental Validation for Unmanned Aerial Vehicles

Unmanned Aerial Vehicles (UAVs) are a viable alternative to manned aircraft and satellites for a variety of applications, including environmental monitoring, agriculture, and surveying. They promise greater precision and much lower operating costs than traditional methods. Critical to the success of UAV systems is the auto-pilot system which keeps the vehicle in the air and in control in the ab...

A Lightweight Hyperspectral Mapping System and Photogrammetric Processing Chain for Unmanned Aerial Vehicles

During the last years commercial hyperspectral imaging sensors have been miniaturized and their performance has been demonstrated on Unmanned Aerial Vehicles (UAV). However currently the commercial hyperspectral systems still require minimum payload capacity of approximately 3 kg, forcing usage of rather large UAVs. In this article we present a lightweight hyperspectral mapping system (HYMSY) f...

Quad - Rotor Unmanned Aerial Vehicle Helicopter Modelling & Control Regular Paper

This paper presents the investigation of the modelling and control of a quad‐rotor helicopter and forms part of research involving the development of an unmanned aerial vehicle (UAV) to be used in search and rescue applications. Quad‐rotor helicopters consist of two pairs of counter rotating rotors situated at the ends of a cross, symmetric about the centre of gra...
