Facade Reconstruction from Aerial Images by Multi-view Plane Sweeping

چکیده
This papers describes an algorithm to estimate the precise position of facade planes in digital surface models (DSM) reconstructed from aerial images using an image-based optimization method which exploits the redundancy of the data set (along and across track overlap). This approach assumes that a facade is a vertical plane and that the heightfield is precise enough to generate hypotheses for the initialization of the optimization algorithm. The initialization is first roughly oriented using the principal line directions of its texture, afterwards a hierarchical algorithm performs a finer optimization to maximize the correlation across different views. The proposed method is applied to real world imagery and its results are shown.

Hierarchical Repetition Extraction for Building Façade Reconstruction from Oblique Aerial Images
In this paper we introduce an approach for automatic recognition and reconstruction of building facade structure from oblique aerial images. Contrast to street-view image oblique aerial image has larger field of view but lower resolution, weaker texture and more noise. To overcome these shortcomings, our approach firstly analyses the horizontal distribution density to extract individual facade ...
متن کاملAutomatic Detection of Buildings with Rectangular Flat Roofs from Multi-view Oblique Imagery
Automatic building detection plays an important role in many applications. Traditionally, buildings were detected from monocular or multi-view images, DEM or DSM, and laser scanner data. Oblique imagery is a relatively new data source with distinct advantages: it provides detailed information on facades and multiple views from various perspectives. In this paper we present exploration tests usi...
متن کاملImproving Image Segmentation Using Multiple View Analysis
In our contribution, we improve image segmentation by integrating depth information from multi-view analysis. We assume the object surface in each region can be represented by a low order polynomial, and estimate the best fitting parameters of a plane using those points of the point cloud, which are mapped to the specific region. We can merge adjacent image regions, which cannot be distinguishe...
