First, the Map Alignment stage, in which the transformation between pairs of local maps is computed. Then, in the Map Merging stage, the data from each local map is fused into a unique map. Particularly, we use the RANSAC method in order to perform the alignment between maps. Then, in ...
During navigation, FreeNavi produces human understandable directions based on landmarks in the virtual map. Evaluation result shows that FreeNavi can build mostly correct maps and provide efficient directions to users despite relying only on WiFi signals. 展开 ...
GPS-based services (e.g. Google Maps) are very popular in our daily life, while there are still many GPS-denied environments (e.g. indoor and underground scenarios) in which they cannot be used. In these situations, localization and navi... H Hua,P Zhang,J Renz - ACM 被引量: 0发表...
In addition, the system includes images of each landmark helping users to navigate visually in addition to through textual instructions and route maps. The system runs on a mobile device; the users use the device's camera to register each landmark's QR code and so update their position (...
From these data, and from background pictorial information, such as maps, landmarks and unsafe areas, the operator can determine the appropriate command in response to a developing situation. The operator can communicate the surveillance ... WC Morchin,SL Johnston 被引量: 14发表: 1991年 加载...

Several studies found out that the design of topographic maps has a systematical influence on spatial memory performance. Within the frame of the Priority Programme SSP 1894 “Volunteered Geographic Information (VGI): Interpretation, Visualisation and Social Computing”, which is funded by the German ...
