“…Li et al (2017) exploited some declassified satellite photographs to derive ice velocity and topography from the early 60's in Antarctica. Examples of processing such kind of data using SfM approach can be found in Cogliati et al (2017) and Feurer and Vinatier (2018).…”

In this paper the use of different types of remote-sensing techniques for monitoring topographic changes of Alpine glaciers is presented and discussed. Close range photogrammetry based on Structure-from-Motion approach is adopted to process images recorded from ground-based and drone-based stations in order to output dense point clouds. These are then directly compared to detect local changes by mean of M3C2 algorithm, while digital elevation models are interpolated to find global ice thinning and retreat. Medium-resolution satellite imagery can be exploited to monitor the glacier evolution at lower resolution but including the development and collapse of large crevasses. A case study concerning the Forni Glacier in the Raethian Alps (Italy) is presented to demonstrate the feasibility of the proposed approach by adopting data sets collected from 2016 to 2018.

“…Furthermore, this paper presents a methodology according to the internal parameters of the metric camera that can be used in the image processing in the current photogrammetric systems. Currently, it is common practice that the issue of identifying the elements of the internal orientation is neglected in the processing of digitized photographs and the issue is left to solve by the self-calibration process in the used photogrammetric system [1][2][3][4][5][6][9][10][11][12].…”

“…Therefore, they are valuable sources of information for the study of a landscape development. In such cases, they can be used as map bases for orthophotos and digital terrain models (DTM) at the time of the aerial photography [1][2][3][4][5][6]. These outputs can be used as separate data layers in Geographic Information Systems (GIS).…”

3d Digital Reconstruction Based on Archived Terrestrial Photographs From Metric Cameras

The paper deals with the possibilities and limitations of the image processing of digitalized terrestrial photographs from analogue metric cameras. By the end of the 20th century, analogue metric cameras such as Zeiss UMK were used for documentation purposes in the fields of industrial and investment construction, nature and landscape preservation, heritage preservation, etc. Currently, the collections of photographs are stored at specialized archives of many different institutions, such as libraries, museums, universities, etc. These sets of photographs provide a material background for a 3D digital reconstruction of a subject of interest at the time of taking the photographs. The digital image processing of old photographs may be more difficult due to unknown parameters of the used camera, such as the focal length, image coordinates of the fiducial marks and distortion parameters of the lens system, etc. In this case, it may be difficult to process these photographs in a photogrammetric software. The paper presents a methodology for the digital photogrammetric processing of analogue terrestrial photographs. The data processing is based on the parameters of the used metric cameras, which are described in their calibration reports. The image processing was tested in two commercial photogrammetric software tools that utilize the technology of Structure-from-Motion (SfM) or multiimage intersection photogrammetry to process image datasets.

“…In literature, Agisoft PhotoScan prevails as a photogrammetric software for processing analogue images. Agisoft PhotoScan was used also by [3] to create 3D model of historic buildings, by [4] to process analogue images captured by RolleiMetric camera and UMK camera of Omayyad mosque, by [5] to analyse historic changes of a glacier, by [6] to process archival images captured by Hasselblad H5D-60 of chosen archeological area, by [7] to process analogue non-metric images and by [8] to process analogue aerial images to create DEM and orthophoto. The open-source MicMac was used for processing analogue images by [9].…”

SfM processing of archived analogue images gives an opportunity to efficiently create new and valuable 2D and 3D results. The SfM processing of digitized analogue images brings some challenges. How to digitize negatives of photogrammetric images? What scanning resolution is the most beneficial for processing? How to preprocess the digitized images to be able to process them using the SfM method? What accuracy of results is possible to expect? This paper tries to deal with all these questions. For this paper, 7 negatives of former photogrammetric documentation of a vault were chosen. The negatives were captured by Rollei 3003 metric camera in 1999. Two pieces of software were chosen for the SfM processing. A commercial alternative Agisoft PhotoScan and free open-source alternative MicMac. The results of the SfM processing were compared to the results of an original photogrammetric method, which was used for former processing in 1999.
