The 3D Optical Metrology (3DOM) unit of the Bruno Kessler Foundation (FBK) in Trento (Italy) has collected VHR satellite imagery, as well as aerial and terrestrial data over Trento for creating a complete testfield for investigations on image radiometry, geometric accuracy, automatic digital surface model (DSM) generation, 2D/3D feature extraction, city modelling and data fusion. This paper addresses the radiometric and the geometric aspects of the VHR spaceborne imagery included in the Trento testfield and their potential for 3D information extraction. The dataset consist of two stereo-pairs acquired by WorldView-2 and by GeoEye-1 in panchromatic and multispectral mode, and a triplet from Pléiades-1A. For reference and validation, a DSM from airborne LiDAR acquisition is used. The paper gives details on the project, dataset characteristics and achieved results.

We previously proposed a manual photogrammetric process based on the Multi Representation Acquisition Pattern (MRAP) concept to tackle simultaneously Fine Level Geometries (FLG) extraction and Coarse Level Geometries (CLG) extraction. This paper presents our progress, from an automation standpoint, regarding our approach to populate MRDBs containing building geometries through a photogrammetric multiple representations acquisition process. Two new algorithms dedicated to Multi Representation (MR) acquisition are introduced and constitute two contributions. These combine passive imagery and Digital Surface Model analysis in order to address automation issues. The first algorithm allows for the automatic determination of the MRAP parameters from a single click initialization. The second algorithm aims at supporting part of the MR acquisition when MRAP are not relevant and allows the automatic building footprints extraction. This paper describes the project motivation and its actual progress. It is divided into four parts. The first part concerns the MR data acquisition specifications. A description of the manual prototype is provided and the MRAP concept is described. In the second part, the first algorithm allowing the automatic determination of the MRAP parameters is introduced. The third part is dedicated to the review of the automation performances through the study of three test sites. Finally, our second algorithm, allowing the automatic building footprints extraction is introduced with preliminary results.

Urban-trees extraction from Quickbird imagery using multiscale spectex-filtering and non-parametric classification / Y.O. Ouma in ISPRS Journal of photogrammetry and remote sensing, vol 63 n° 3 (May - June 2008)  

Public [article]  inISPRS Journal of photogrammetry and remote sensing > vol 63 n° 3 (May - June 2008) . - pp 333 - 351 Titre : Urban-trees extraction from Quickbird imagery using multiscale spectex-filtering and non-parametric classification Type de document : Article/Communication Auteurs : Y.O.

The main drawback of these methods is that they neglect the shape and context aspects of the image information, which are among the main clues for information extraction at very-high spatial resolutions. This paper presents a pre-classification filtering strategy based on unsupervised multiresolution non-linear image filtering that combines spectral and textural (spectex) image characteristics. In a multiscale model, the local texture characteristics are extracted via wavelet decomposition. The multiscale wavelets texture is then used to control the multiresolution spectral filtering process using the non-linear anisotropic diffusion approach. From the multiresolution non-linear filtering procedure, scale sub-bands suitable for urban-trees extraction are selected. The selected bands are integrated with a normalized difference vegetation index (NDVI) and a principal components transformation (PCT) for classification using a decision-tree (DT) non-parametric classifier. The DT results are compared with the statistical maximum-likelihood classifier. It has been demonstrated that with Quickbird imagery a classification based on the filtered imagery improved the extraction accuracy of urban-trees by 11.7% using the parametric maximum-likelihood classifier, and by 22.5% using the non-parametric decision-tree classifier. This is an increase from a 70.8% extraction accuracy when the respective methods are not used. The results further indicate that the non-linear filtering approach is superior to the linear (median) filtering technique, by 20.8% with respect to classification accuracy.

Data sets from two test sites were delivered to the twelve participants of the project. For each test site the following data were available and could be downloaded from the FGI ftp-site: aerial images, camera calibration and image orientation information, ground control point coordinates and jpg-images of point locations, laser scanner data with three different pulse densities, digital terrain model and a training data set. In this report the test sites used, data sets and the reference data are described. The tree extraction methods used by the participants and methods used in accuracy evaluation are explained in this report. The produced tree models are depicted and analysed with respect to tree location, tree height, crown base height and crown delineation accuracy. Finally, a discussion and conclusions chapter summarise the results of the project. Surprisingly, results show that the extraction method is the main factor on the achieved accuracy. When the laser point density increases from two points to eight points per m2, the improvement in crown base height and crown delineation accuracy is marginal but in the case of some methods the accuracy of the tree location and especially the tree height determination improves. The low number of hybrid models based on both the laser data and aerial image produced by the partners implies that integration of laser and aerial image is in its early stages.

Geometric Correction and Digital Elevation Extraction Using Multiple MTI Datasets / J.A. Mercier in Photogrammetric Engineering & Remote Sensing, PERS, vol 73 n° 2 (February 2007)

Standard DEM extraction techniques can be naturally extended to satellite imagery, but the particular characteristics of satellite imaging can cause difficulties. The spacecraft ephemeris with respect to the ground site during image collects is the most important factor in the elevation extraction process. When the angle of separation between the stereo images is small, the extraction process typically produces measurements with low accuracy, while a large angle of separation can cause an excessive number of erroneous points in the DEM from occlusion of ground areas. The use of three or more images registered to the same ground area can potentially reduce these problems and improve the accuracy of the extracted DEM. The pointing capability of some sensors, such as the Multispectral Thermal Imager (MTI), allows for multiple collects of the same area from different perspectives. This functionality of MTI makes it a good candidate for the implementation of a DEM extraction algorithm using multiple images for improved accuracy. Evaluation of this capability and development of algorithms to geometrically model the MTI sensor and extract DEMs from multi-look MTI imagery are described in this paper. An RMS elevation error of 6.3-meters is achieved using 11 ground test points, while the MTI band has a 5-meter ground sample distance.
