Current Internet-inspired mapping data are in the form of street maps, orthophotos, 3D models or street-side images and serve to support mostly search and navigation. Yet the only mapping data that cu...
为了解决了常规裸眼3D显示器件视区固定,且观看角度狭小的问题,文中提出一种基于头部追踪技术的增大观看视角的解决方案。该方案可以通过头部追踪设备检测观看者所在的位置,通过调整液晶光栅的透光位置,使观看者的左眼与右眼分别位于最佳观看区域,在很大范围内,观看者始终可以看到合适的3D图像。提出了头部追踪3D显示器件的测试评价方法,通过实验室验证,该方法能有效评价该类显示器件的性能。

In modern road surveys, hanging power cables are among the most commonly-found geometric features. These cables are catenary curves that are conventionally modelled with three parameters in 2D Cartesi...
This paper presents the first experience of a close range bird's eye view photogrammetry with range imaging (RIM) sensors for the real time generation of high resolution geo-referenced 3D surface mode...
An automated model-image fitting algorithm is proposed in this paper for generating façade texture image from pictures taken by smartphones or tablet PCs. The façade texture generation requi...
Since remote sensing provides new sensors and techniques to accumulate stereo data on urban regions, three-dimensional (3D) repre- sentation of these regions gained much interest for various applicati...
In the context of increasing greenhouse gas emission and global demographic change with the simultaneous trend to urbanization, it is a big challenge for cities around the world to perform modificatio...
Aerial laser scan data is widely used to produce 2 1/2D digital elevation models automatically. However, creating full 3D city models from this data is a complex task. A simplified 3D model, like a 2 ...
Cultural heritage is a complex and diverse concept, which brings together a wide domain of information. Resources linked to a cultural heritage site may consist of physical artefacts, books, works of ...
This paper presents the problem of the current separate treatment of levels of detail in city models. We propose a solution, detail the main principles, and present our initial results on the approach...
A novel autostereoscopic display with high resolution of 2D and 3D images and wide viewing angle was proposed by combining an “active scanning film” and fast response panel. The Multi-Electrode Drivin...
This paper presents an alternative approach for achieving higher optical efficiency in conventional parallax barrier 3D mobile displays. The method entails modifying and enhancing the protrusion struc...
Using a 2-view Autostereoscopic 3D Projection display system, a radically designed projection screen film system coupled with a conventional projection display is herein presented and shown to produce...
GIS integrated 3D modelling is crucial for the city planning and design processes because urban modelling is a tool used in virtual environments, and provides convenience to work. Although, the creati...
