Multi-image Fusion for Occlusion-free Façade Texturing
نویسنده
چکیده
Façade texturing is a key point for realistic rendering of virtual city models, since it suggests to the viewer a level of detail that is much higher than actually provided by the geometry. Façade textures are usually derived from terrestrial imagery acquired from a position on the ground. One problem frequently encountered is the disturbance of texture images by partial occlusion of the façade with other objects. These occluding objects can be moving objects such as pedestrians and cars or static objects such as trees and street signs. This paper presents a method for the detection and removal of these disturbances and allows for the generation of occlusion-free texture images by multi-image fusion.

The purpose of multi-focus image fusion is gathering the essential information and the focused parts from the input multi-focus images into a single image. These multi-focus images are captured with different depths of focus of cameras. A lot of multi-focus image fusion techniques have been introduced using considering the focus measurement in the spatial domain. However, the multi-focus image ...

The building façade model is the most prominent streetscape feature for rendering virtual street models. This paper aims to develop a method to identify street obstacles which hinder photo-realistic texturing of building façade. In order to achieve this, the presented method focuses on two research components. Firstly, we develop an effective grid-based line analysis method to differentiate ima...
متن کاملAutomatic generation of façade textures from terrestrial thermal infrared image sequences
This paper discusses the automatic texturing of building facades from thermal infrared image sequences. A fully automatic method is presented to refine GPS based positions using a relative orientation of the image sequence and preknowledge of a given building model in a bundle adjustment process. The resulting refined orientation parameters are used to project the infrared images of the sequenc...

متن کاملOcclusion-free Image Generation for Realistic Texture Mapping
Photo-realistic 3D models are nowadays required in many applications. The 3D modelling pipeline can be imageor range-based and often ends up with a visualization of a virtual textured model. One of the main problems encountered in texture mapping is the disturbance in the images by occlusions, which do not allow the generation of photo-realistic textured 3D models. Occlusions can be moving (e.g...
