The unsteady and nonlinear aerodynamic characteristics of the Meridian unmanned aerial system in the presence of wind shear are investigated using the recorded test data during flights in Polar Regions. The Meridian UAS is designed to provide an aerial platform for ice-penetrating radar developed for research in Polar Regions. The Meridian Unmanned Aerial Vehicle (UAS) is a 499 kg (1,100 pounds...

Along with the progress of each basic theories in the picture science, the numerical picture processing technique gets the extensive application in each section of national economy, moreover, it has become study hotspot that is automatic identify in panchromatic aerial image. A kind of MF method to extract airport in aerial image was put forward on analysing template match and characteristic ex...

This study aims to resolve the problem of not being able to directly examine forests or each individual tree of a forest. In order to get the specific information on actual trees. Such as their locations, heights and the number of trees. We used an aerial photograph that is 4096x4096 pixels. And process the DSM/DEM data with a raw 16 bit-‘unsigned short’ data value. Through the collected inform...

One of the most critical activities of remote sensing consists of the identification of different coverages (types of crops) on land surface. This task is complicated when the entire plot is not covered by the crop (e.g. almond and olive fields, vineyards, etc.). In this paper, the segregation of these crops is accomplished by using a multi-channel (Gabor functions) filtering approach in remote...

A discussion on a new and novel approach for registering an image on a 3D model will be given. The approach was developed based on registering a mono aerial photograph on laser scanning data and did not require camera and photograph calibration parameters for processing. In contrast conventional approaches which their outputs are a raster image and are presented on a 2D plan, the output from th...

In this study two aerial photograph interpretation methods, visual and digital classification, were used for the aquatic macrophyte mapping of a eutrophic study lake in the Finnish Lake District. The study indicated that aerial photograph interpretation is a useful monitoring method of aquatic macrophytes in lakes dominated by helophytes and nymphaeids. Visual classification produced the taxono...
