Mcmc Linked with Implicit Shape Models and Plane Sweeping for 3d Building Facade Interpretation in Image Sequences
نویسندگان
چکیده
In this paper we propose to link Markov Chain Monte Carlo – MCMC in the spirit of (Dick, Torr, and Cipolla, 2004) with information from Implicit Shape Models – ISM (Leibe and Schiele, 2004) and with Plane Sweeping (Werner and Zisserman, 2002) for the 3D interpretation of building facades, particularly for determining windows and their 3D extent. The approach starts with a (possibly uncalibrated) image sequence, from which the 3D structure and especially the vertical facades are determined. Windows are then detected via ISM. The main novelty of our work lies in using the information learned by the ISM also to delineate the window extent. Additionally, we determine the 3D position of the windows by plane sweeping in multiple images. Results show potentials and problems of the proposed approach.

Automatic 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 کاملBuilding Façade Interpretation from Image Sequences
In this paper we propose an approach for building façade interpretation ranging from uncalibrated images of an image sequence to the extraction of objects such as windows. The approach comprises several novel features, such as determination of the façade planes by robust least squares matching, learning of implicit shape models for objects, particularly windows, and a determination of the latte...
متن کاملOrtho-rectified Facade Image by Fusion of 3d Laser Data and Optical Images
Obtaining three-dimensional models of urban scenes from sensor data is a challenging topic. The construction of 3D city models requires fusion of data coming from different sensors, such as laser scanners and cameras. At a first phase, we will process building facades, which will be considered as textured 3D planes. The acquisition system is equipped with two laser scanners and many (twelve) ca...
