This paper presents a new method for creating a 3D virtual broad city environment with walk-through systems based on Image-Based Rendering(IBR). In that virtual city, people can move rather freely and look at arbitrary views. The strength of our method is that we are able to easily render any view from an arbitrary point to an arbitrary direction on the ground in a virtual environment; previous...

In resent years, remote sensing technologies are utilized in disaster management as a means of information gathering in a large scale disaster. QuickBird captured a clear image of Bam City, eight days after the 2003 Bam, Iran, earthquake. The city was also observed by QuickBird about three months before the event. In this paper, we perform building damage detection based on land cover classific...

This work employs a fish-eye to scan cityscapes along a street and register scenes in a compact scene tunnel image. A fish-eye has complete field of view along a route. We mount the fish-eye camera on a vehicle and estimate its pose initially with respect to the vehicle by referring to 3D structure lines of such as roads and buildings on a street. Sampling curves are then allocated in the image...

This paper summarizes the first results on interferometric ENVISAT/ ASAR image mode products [1]. We analyzed timing and geometric accuracy as well as the phase of a first interferogram from an IS2 image mode data set (VV polarized). According to the schedule the image mode products of this beam products are the first to be validated [2]. This interferogram is one of the first ENVISAT/ ASAR int...

In this sketch we present an interactive real-time city generation system. The aim of such a system is to apply procedural techniques to rapidly generate detailed city models suitable for use in graphics applications. Most commonly, the underlying road network for the city is generated first and is used as a basis for positioning buildings and other features. Existing work includes CityEngine [...

This paper introduces the universal mobile interface that allows users to navigate themselves into multiple heterogeneous digital cites with a single interface. The universal mobile interface connects a map-based information search system, an image-based virtual city space, and a 3D virtual city space, that had been developed independently. A user can walk-through the above systems simultaneous...

Digital panoramic photography has become a popular tool to record landscapes, city squares or indoor scenes in a single image with a full 360° view. In photogrammetric applications, a digital panoramic camera may present an interesting alternative to conventional image acquisition techniques such as large format film or plate based cameras. Advantages of such a camera are their very high resolu...
