Digital still cameras have been widely adopted for close range photogrammetry and machine vision applications. Due to the advantages of on board storage of digital images, portability and rapid data processing, digital still cameras have virtually replaced medium format film cameras for measurement tasks such as structural monitoring and industrial metrology. As for any photogrammetric applicat...

Linear array CCD-based panoramic cameras are being used also in measurement applications. The elegant image acquisition mode and the high information content of those images make them suitable candidates for quantitative image analysis. The best possible accuracy is acquired by a suitable sensor model and following the concept of network design. In our previous investigations we designed a sens...

The purpose of our study is to test close range photogrammetry as an engineering tool, in an architectural project for two different sites. The first is an urban site in Reims (Champagne, France), where we are studying the conversion of an eight hectares wide waste ground, left vacant following old military barracks. The second is the old malt house of Ingwiller (Alsace, France), where it is ne...

The physical and generalized sensor models are two widely used imaging geometry models in the photogrammetry and remote sensing. Utilizing the rational function model (RFM) to replace physical sensor models in photogrammetric mapping is becoming a standard way for economical and fast mapping from high-resolution images. The RFM is accepted for imagery exploitation since high accuracies have bee...

Photogrammetric techniques are used for the generation of point cloud data. Multiple images acquired with photo cameras are processed into dense point clouds using photogrammetric workflows. These are normally based on a basic photogrammetric workflow with three steps: tiepoints detection; estimation of camera positions and orientations and of calibration parameters; and dense-matching point cl...

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...
