چکیده
In this section we provide the form of the projection functions Pv(`, c) that convert from geographic locations to pixel locations in aerial view and street view images. We give the form of the inverse function P−1 v (`′, c) that converts from pixel locations to geographic coordinates. Aerial images: Aerial view imagery in Google maps is represented using a Web Mercator projection, a type of cylindrical map projection that unwraps the spherical surface of the earth into a giant rectangular image. A pixel location `′ = (x, y) is computed from a geographic location ` = (lat, lng) in radians, as (x, y) = Pav(lat, lng):

Urban 3d Modelling Using Terrestrial Laser Scanners
This paper describes a technique for 3D Reconstruction of large outdoor areas using terrestrial laser scanning. It presents the paradigm for automated 3D registration and requirements of the positioning and orientation subsystem to handle fully automatic 3D registrations. It analyzes the different problems and difficulties associated with such type of environments, including the analysis of sca...
متن کاملUrban Object Extraction from Digital Surface Model and Digital Aerial Images
The paper describes two different methods for extraction of two types of urban objects from lidar digital surface model (DSM) and digital aerial images. Within the preprocessing digital terrain model (DTM) and orthoimages for three test areas were generated from aerial images using automatic photogrammetric methods. Automatic building extraction was done using DSM and multispectral orthoimages....
متن کاملAn Improved Car Detection using Street Layer Extraction
Automatic 3D modeling of urban environments has recently become a hot research topics since location aware applications (e.g. Virtual Earth, Google Earth) on the Internet aim for detailed models of the earth. In large scale 3D city models, moving objects, such as cars usually bear errors and distract the automatic reconstruction process. Therefore it is desirable to detect and remove these obje...
متن کاملCombining Multiple Data Sources for Urban Data Acquisition
One of the most promising approaches to solve the challenging task of thematic mapping in urban environments is the integration of multiple data sources to benefit from the complementary types of available information. Within the paper the combination of Digital Surface Models (DSM) resulting from airborne laser scanning and colour aerial imagery for landuse classification in urban environments...
متن کاملDiscrimination between Urban Area and Vegetation in High- Resolution Images Using Markov Random Fields (mrf)
The automatic extraction of traffic data from digital images is a challenging task and implies an extensive pre-processing of this data. An important information which simplifies the further extraction of traffic objects is the recognition of active traffic regions. A possible approach is masking of streets using platform attitude and position together with a digital street map (i). But often s...
