The Indo-Gangetic basin is one of the productive rice growing areas in South-East Asia. Within this extensive flat fertile land, lower Gangetic basin, especially the south Bengal, is most intensively ...
为实现移动机器人环境探知并直观表现的功能,设计一种以前方180°为范围的简单几何地图绘制系统。该系统采用lpc1768 为核心,下位机部分以小型舵机MG90S 和超声模块HC-SR04 的云台组合为基础,上位机通过CVI 编写的程序对下位机测量的数据进行处理,将其通过上位机界面以二维地图形式直观表现;并通过探测3 种障碍地图进行验证。实验结果表明:该系统能准确反映机器人前方的环境信息,适用于移动机...
The periodic inspection of certain infrastructure features plays a key role for road network safety and preservation, and for developing optimal maintenance planning that minimize the life-cycle cost ...
Traffic sign provides road users with the specified instruction and information to enhance traffic safety. Automatic detection of traffic sign is important for navigation, autonomous driving, transpor...
A new method for high resolution surface reconstruction by multi-image matching in object space is formulated with regard to the integration of a general 3-d surface model in object space, because com...
The authors have developed a new method called "Polygon Shift Method" (named by the first author) that enables to generate bird's eye view of topographic landscape with shade and shadow. The Polygon S...
A geologic map provides information about the currently accepted model regarding the subsurface structures in a given area. It is based on various types of information such as field observations, dril...
The estimation of accuracy of thematic maps derived from remotely sensed data used in conjunction with a geographic information system is presented. A systematic random sampling techique is proposed t...
In order to have an integrated view of an urban area, it is necessary to show the terrain and the structures on it. There are many established computer programs that can do efficiently either task ind...
Virtual reality applications in the context of urban planning presume the acquisition of 3D urban models. Photo realism can only be achieved if the geometry of buildings is represented by a detailed a...
