Building Reconstruction Using Line Matching and Intersection from Multiple Aerial Images
نویسندگان
چکیده
Line matching plays an important role in building reconstruction, because majority buildings are composed of line segments along boundaries. Considering the complexity in image processing, line matching is a challenging work. The building reconstruction with line matching algorithm is performed using high overlapping aerial images in this study. The strategy is to determine the building boundaries first followed by the processing of the roof structures. The basic procedures in those two parts are similar with the differences of parameter settings. First, extracting the straight lines and using left-right matching to locate the conjugate lines in multiple images. Then, space line intersection is employed with blunder detection for 3D line positioning. The reconstruction and refinement processes are done in an iterative way. The experimental results indicate that the proposed method can reach reliable results. Keyword: Left-right Matching, Space Line Intersection, Blunder Detection, Building Reconstruction

متن کاملExtracting 3d Edgel Hypotheses from Multiple Calibrated Images: a Step towards the Reconstruction of Curved and Straight Object Boundary Lines
This paper describes a novel technique to extract elementary linear elements from multiple views, often called edgels, that are 3D points with tangent direction. Techniques based on stereopair feature, edgel or contour, matching have been intensively developed in the 80s. The relatively poor quality of images used at the time and the ill-posed stereo context contributed to focus the research ar...
