Assessment of digital elevation models using RTK GPS
A Digital Elevation Model (DEM) represents the height of a patch of terrain. Accuracies of DEMs vary depending upon the requirements of different applications. DEMs have been applied to a wide range of civil engineering and military planning tasks. Besides the conventional methods of creating DEMs, such as photogrammetry and manual field survey, airborne laser scanning and radar interferometry ...
متن کاملMMW-Scanning Radar for Descent Guidance and Landing Safeguard
This paper explores the use of millimeter-wave (MMW) scanning radar for control and safeguarding during spacecraft descent and landing. The essay compares radar characteristics such as beam width, agility and range accuracy, against sensing requirements for a specific descent and landing scenario. While the study discussed here presents the advantages of agile motion-free scanning radar for map...
متن کامل3-D measurements from imaging laser radars: how good are they?
In this paper we analyse a class of imaging range finders amplitude-modulated continuous-wave laser radars in the context of computer vision and robotics. The analysis develops measurement models from the fundamental principles of laser radar operation, and identifies the nature and cause of key problems that affect measurements from this class of sensors. We classify the problems as fundamenta...
متن کاملMap Building for a Terrain Scanning Robot
This paper presents the application of an image registration method for a mobile manipulator. The robot is used for scanning natural terrain and detecting metal objects hidden beneath the terrain surface (e.g., landmines) using a metal detector. The range image may be interpreted for visual servoing, map building and path planning, or object recognition. In this work, the image is used to build...
متن کاملLandforms identification using neural network-self organizing map and SRTM data
During an 11 days mission in February 2000 the Shuttle Radar Topography Mission (SRTM) collected data over 80% of the Earth's land surface, for all areas between 60 degrees N and 56 degrees S latitude. Since SRTM data became available, many studies utilized them for application in topography and morphometric landscape analysis. Exploiting SRTM data for recognition and extraction of topographic ...
