PDA based navigation system for a 3D environment
Navigation systems are an important application in the field of mobile computing. In order to increase the usability of navigation systems it is desirable to present information in a form that is most informative for the user. This paper deals with the possibility of presenting the information in a 3D form that provides the user with more information than information in a 2D form. A concept of ...
متن کاملA Wireless Ultrasonic Ndt Senor System
Ultrasonic condition monitoring technologies have been traditionally utilized in industrial and construction environments where structural integrity is of concern. Such techniques include active systems with either single or multiple transmit-receiver combinations used to obtain defect positioning and magnitude. Active sensors are implemented in two ways; in a thickness operation mode, or as an...
متن کاملInertial Pocket Navigation System: Unaided 3D Positioning
Inertial navigation systems use dead-reckoning to estimate the pedestrian's position. There are two types of pedestrian dead-reckoning, the strapdown algorithm and the step-and-heading approach. Unlike the strapdown algorithm, which consists of the double integration of the three orthogonal accelerometer readings, the step-and-heading approach lacks the vertical displacement estimation. We prop...
متن کاملdesigning and implementing a 3D indoor navigation web application
During the recent years, the need arises for indoor navigation systems for guidance of a client in natural hazards and fire, due to the fact that human settlements have been complicating. This research paper aims to design and implement a visual indoor navigation web application. The designed system processes CityGML data model automatically and then, extracts semantic, topologic and geometric...
متن کاملVision based navigation system
A vision based navigation system to guide an endoscope inside a human colon has been designed and tested. It uses low level vision techniques to extract two types of navigational landmarks, dark regions and curved contours. Dark regions correspond to the distant inner space of the colon, called the lumen. The curved contours represent occlusions due to the inner colon muscles. A hierarchical se...
