Mixed or Augmented Reality (AR) systems align computer generated virtual objects and real world objects with each other to enhance the vision of the physical reality with the virtual objects in a manner, that will allow a user to interact with spatial data in his natural environment and scale (1:1). Especially when dealing with natural disasters the(More)
Currently, enhanced types of active range imaging devices are available for capturing dynamic scenes. By using intensity and range images, data derived from different or the same range imaging devices can be fused. In this paper, an automatic image-based co-registration methodology is presented which uses a RANSAC-based scheme for the Efficient(More)
In this paper, we present a generic, modular bundle adjustment method for pose estimation, simultaneous self-calibration and reconstruction for multi-camera systems. In contrast to other approaches that use bearing vectors (camera rays) as observations, we extend the common collinearity equations with a general camera model and include the relative(More)
—Cities have always been considered a horsepower of industrial growth over centuries. However, urbanization often has environmental effects. In this paper we will focus on one of them, namely air pollution, and how we can integrate 3D city models and air quality sensor data. In most cases, air quality data is acquired from static sensor systems like weather(More)
