Dense Image Matching

Performance Analysis on Oblique Imagery

3D reconstruction using dense image matching is a hot topic as it enables the automatic extraction of 3D urban models, notably from airborne oblique imagery. However, applying DIM algorithms to oblique imagery is challenging because of large scale variations, illumination changes and the many occlusions. Here, the authors present a methodology for evaluating the performance of DIM algorithms and show the initial results from four DIM packages: Agisoft PhotoScan, Leica Xpro SGM, OpenCV StereoSGBM and SURE. Dense image matching (DIM) aims at computing a depth value for each and every pixel of an image. This facilitates the generation of accurate... (read more)

Stereo-matching Techniques

Automation in photogrammetry is largely made possible by stereo-matching techniques that enable (semi-)automatic aero-triangulation and creation of digital elevation models. Matching: I know what it is, I know what it does, but how does it work? The aim of matching is to identify corresponding phenomena in two or more sets. In photogrammetry the sets are the left and right image of a stereo pair, and the problem in corresponding them is to trace and locate in the right image the conjugate of a point in the left image. Ever since images could be stored in a computer as pixels stereo-matching... (read more)

Dense Image Matching

Point clouds are increasingly a prime data source for 3D information. For many years, Lidar systems have been the primary way to create point clouds. More recently, advances in the field of computer vision have allowed for the generation of detailed and reliable point clouds from images – not only from traditional aerial photographs but also from uncalibrated photos from consumer-grade cameras. Dense image matching is the powerful technology underpinning this development. (By Martin Kodde) Understanding photogrammetry A good understanding of dense image matching requires insight into the way photogrammetry works. Photogrammetry in itself is not a new technology; it...

Geo Databases

This product survey is the third in a series entitled ‘Spatial Data Management in Geo databases’ (‘RDBMS’). A trend can be observed in integration of spatial data with other attributes in Relational DataBase Systems. The Open Geospatial Consortium succeeded in the development and provision of a comprehensive set of OpenGIS standards related to spatial data management adopted by the GIS and database industries, including the Geography Markup Language. Watching today’s Geo database market one learns that the functionality of some Geo database products have evolved. Oracle for example supports planar topology with Oracle 10g. This enables topology to be validated... (read more)

Geo-economics

Geographical analysis must form the basis of any strategy for economic development of a region. Jeffrey Sachs, director of the Earth Institute at Columbia University in New York and writer of best-sellers The End of Poverty and Common Wealth , Economics for a Crowded Planet is clear on this point. The role of geography, geo-information or geospatial analysis cannot be overestimated as a determining factor in today’s policy-making for a better world. Sachs, in a keynote speech to the congress of the American Association of Geographers in Boston on 15th April, described six areas where geography in its many... (read more)
