[Termes IGN] tâche image d'un pointRésumé : (auteur) This paper proposes a method to estimate the local sharpness of an optical system through the wavelet-based analysis of a large set of images it acquired. Assuming a space-invariant distribution of image features, such as in the aerial photography context, the proposed approach produces a sharpness map of the imaging device over 16x16 pixels blocks that enables, for instance, the detection of optical defects and the qualification of the mosaicking of multiple sensor images into a larger composite image. The proposed analysis is based on accumulating of the edge maps corresponding to the first levels of the Haar Transform of each image of the dataset, following the intuition that statistically, each pixel will see the same image structures. We propose a calibration method to transform these accumulated edge maps into a sharpness map by approximating the local PSF (Point Spread Function) with a Gaussian blur.

[Termes IGN] point d'appuiRésumé : (Auteur) The main obstacle to achieving high precision in georeferencing from high-resolution satellite imagery (hrsi) remains the need for provision of good quality ground control points (GCPs), whether the GCPs are used to remove biases in RFC triangulation or to support physical sensor orientation models. The provision of GCPs can be very costly and is often not feasible in remote regions, the very areas where mapping from satellite imagery shows significant potential. In order to drastically reduce the number of GCPs required for georeferencing from HRSI, a generic sensor orientation model incorporating strip adjustment capability has been adopted. Under this approach, the metadata for each separate scene is merged to produce a single, continuous set of orbit and attitude parameters, such that the entire strip of tens of images can be treated as a single image. The merging of orbit data results in a considerable reduction in both the number of unknown parameters and the number of required GCPs in the sensor orientation. RPCs are then generated from the adjusted orientation data for each image forming the strip or block. Application of the method to very long strips of ALOS PRISM imagery is reported in this paper. The results of experimental testing indicate that one-pixel level accuracy can be achieved over strip lengths of more than 50 ALOS images, or 1,500 km, with as few as four GCPs.

Currently, integration of laser data and images provides the most complete information for various surveying and 3D modelling tasks. However, this integration requires that both data sets are accurately oriented to the same coordinate system. In 2008, the EuroSDR launched the project "Registration Quality - Towards Integration of Laser Scanning and Photogrammetry" in order to collect knowledge about current registration methods and their performance. The project attracted the involvement of numerous research institutes and companies. Therefore, this test gives a quite extensive set of examples and comparisons of the most important registration strategies today. The empirical results indicated that the relative orientation of airborne laser scanning data and aerial images is a feasible method in order to get data sets within the common coordinate frame. The experiment revealed that, currently, the level of automation was not the most significant factor affecting the quality of registration. More important factors included the type of tie features and the implementation of the methods. The processing time was shortest with most automatic methods, whereas the amount of manual work tended to increase the processing times. It should be noted that many of the methods were still at the developmental stage. It is expected that the performance and processing speed, in most cases, can be enhanced in the future. The test data represented an urban area and many of the methods relied upon certain objects, such as buildings. Therefore, the performance of applied methods in non-built environments should be investigated separately. ;
(Auteur)2 : This report is the final report of the EuroSDR project "Atlas of INSPIRE Implementation Methods". In two two-day workshops and one pre-workshop of the INSPIRE Conference in Krakow, June, 2010 we investigated strategies to implement INSPIRE in several members states. We focused specifically on the relations between the implemented strategy and how successful the INSPIRE implementation is perceived in a specific country. A questionnaire was carried out as well. This report describes the project, presents the conclusions and contains the main deliverables of the project which are: -Two workshop reports - Research agenda for the implementation of INSPIRE -A network of SDI-practitioners and scientists across Europe that are strongly involved in the development of INSPIRE SDI-strategies -Scientific paper publications Scientific paper publications: published IJSDIR article [1] and article in progress for CEUS (Journal for Computers, Environment and Urban Systems) -INSPIRE-Conference pre-conference workshop, abstract and presentation -Key documents collection regarding INSPIRE-implementation -Prototype INSPIRE atlas (see: http://www.spatialist.be)Note de contenu : Registration quality - towards integration of laser scanning and photogrammetry
