The Use of Close Range Photogrammetry for Studying Ice Accretion on Aerofoil Sections
نویسندگان
چکیده
This paper describes the use of photogrammetry to measure and quantify ice accretion on an aerofoil section. A series of stereoscopic photographs was taken during the ice accretion on the section in an icing tunnel. From measurements made on these photographs with a Kern (Leica) DSR 14 analytical photogrammetric plotter, a series of three dimensional models of the ice surfaces was constructed. The results of the project are discussed and possible improvements in the methodology are suggested.

متن کاملMeasuring glacier surface roughness using plot-scale, close-range digital photogrammetry
Glacier roughness at sub-metre scales is an important control on the ice surface energy balance and has implications for scattering energy measured by remote-sensing instruments. Ice surface roughness is dynamic as a consequence of spatial and temporal variation in ablation. To date, studies relying on singular and/or spatially discrete two-dimensional profiles to describe ice surface roughness...

The limitation of land in big cities has caused the vertical growth of cities; for example, high-rise buildings on the ground and underground urban facilities can be mentioned. This restriction has increased the value of land in cities, and on the other hand, it has created some new and complicated technical and legal aspects in the cadastral issues. To respond to these new technical and legal ...

By far, many stereo-matching techniques have been successfully proposed and applied in digital aerial photogrammetry. However, due to some problems such as large parallaxes, occlusions, geometric deformations, and repetitive patterns in convergent close range images, these methods may not be applicable to the same level of success as that of aerial imagery. In order to overcome these shortcomin...
