This paper designs and actualizes independently a set of the aerial photogrammetric system by the low altitude unmanned biplane for satisfying with the request of three-dimensional stereoplotting and ...
More and more analogue cameras are replaced by digital aerial cameras, which is a major change for the industry in various aspects.
Small format aerial imaging sensors are important data acquisition tools, but their positive attributes are too often overlooked.Nowadays, as the number of users of spatial data are dramatically incre...
In this paper we give a detailed description of the photogrammetric workflow recommended for the large format digital aerial camera UltraCamX. This includes image pre-processing, automated aerotriangu...
A test area north of Philadelphia was flown with Vexcel Imaging UltraCamD, UltraCamX and Z/I Imaging DMC digital frame cameras as well as with the 3D-CCD-line scanner camera Leica ADS40 and the analog...
Integration of airborne laser scanning (ALS) point clouds and aerial images has a great potential for accurate and robust 3D modeling and recognition of objects in our environment. The integration req...
Various methods exist for automatic registration of different kinds of image datasets. The datasets could be aerial or satellite images, maps, LiDAR data, etc. In this paper we propose a method for th...
In this study, a robust methodology for the detection of buildings from a single color aerial image is proposed. The methodology is initialized with the mean-shift segmentation algorithm. Next, a ve...
Texture measures are commonly used to increase the number of input bands in order to improve classification accuracy, especially for panchromatic or true colour imagery. While the use of texture mea...
A classification tree based approach for building detection was tested. A digital surface model (DSM) derived from last pulse laser scanner data was first segmented and the segments were classified in...
An entire single-tree remote sensing (STRS) system was developed and tested in an inventory of timber resources of a 56.8-hectare forest. A semi-automatic approach with operator intervention is used i...
Today, mapping technologies are in the midst of transition, from analogue and analytical to digital. The move to digital is being driven by the desire to increase production capability through compute...
Forest boundary delineation is one of the key issues of forest management for Swiss National Forest Inventory (NFI). The proposed approach in this paper focuses on the delineation of forest boundaries...
Based on a first prototype, an improved low-cost aerial platform was developed at the Institute of Digital Image Processing in order to be used for immediate acquisition and processing of image data w...
A complete single-tree remote sensing (STRS) system is presented and a restricted test of performance is given. The system can be used for solving the tasks of STRS: tree positioning, height estimatio...
