Automatic Roof Outlines Reconstruction from Photogrammetric Dsm
The extraction of geometric and semantic information from image and range data is one of the main research topics. Between the different geomatics products, 3D city models have shown to be a valid instrument for several applications. As a consequence, the interest for automated solutions able to speed up and reduce the costs for 3D model generation is greatly increased. Image matching technique...
متن کاملProduction System for Autonomous 3-dimensional Modeling with Lidar, Ifsar, and Photogrammetric Dsm Data
We describe an autonomous production system that utilizes Computational Fluid Dynamics (CFD) techniques and Partial Differential Equations (PDEs) to create accurate textured 3D site models with LiDAR, IFSAR, and stereo imagery. LiDAR is the data set of choice for specific urban scenes. IFSAR or stereo imagery is used for broad areas to mitigate cost. A high resolution Digital Surface Model (DSM...
متن کاملIntegration of photogrammetric DSM and advanced image analysis for the classification of urban areas
In this paper, a technique for the integration of images and point cloud for urban areas classification is presented. A set of aerial RGB overlapping images are used as input. A photogrammetric Digital Surface Model (DSM) is firstly generated by using advanced matching techniques. Subsequently, a thematic classification of the surveyed areas is performed considering simultaneously the surface’s...
متن کاملPhotogrammetric Pavement Detection System
This paper introduces a complex, low-cost road pavement measurement system designed primarily for pothole and crack detection. The onboard system is composed of a GPS/INS navigation unit, an image acquisition module, and a photogrammetric and imageprocessing subsystem. Due to the use of structured light and the availability of accurate navigation data, the 3D coordinates of the road points, in ...
متن کاملMATLAB and photogrammetric applications
Many automated processes in digital photogrammetry such as relative orientation of a stereopair of aerial images or a derivation of a digital terrain model (DTM) are based on image matching. Several approaches to image matching have been developed. In this paper, attention is paid to area based matching. Using of MATLAB in procedures of finding parameters of exterior orientation of an aerial im...
