GPS Navigation for Outdoor and Indoor Environments
The Global Positioning System (GPS) is an accurate positioning system. The GPS has an accuracy that varies from 4mm up to 11m. This project in lieu of thesis investigates the state of art of the GPS navigation and positioning for outdoor and indoor environments with a particular focus to the outdoor applications. This project includes an overview of GPS system, the GPS segments, the composition...
متن کاملIndoor Positioning Using GPS Revisited
It has been considered a fact that GPS performs too poorly inside buildings to provide usable indoor positioning. We analyze results of a measurement campaign to improve on the understanding of indoor GPS reception characteristics. The results show that using state-of-the-art receivers GPS availability is good in many buildings with standard material walls and roofs. The measured root mean squa...
متن کاملRobust Mapping and Localization in Indoor Environments Using Sonar Data
In this paper we describe a new technique for the creation of featurebased stochastic maps using standard Polaroid sonar sensors. The fundamental contributions of our proposal are: (1) a perceptual grouping process that permits the robust identification and localization of environmental features, such as straight segments and corners, from the sparse and noisy sonar data; (2) a map joining tech...
متن کاملMatterport3D: Learning from RGB-D Data in Indoor Environments
Access to large, diverse RGB-D datasets is critical for training RGB-D scene understanding algorithms. However, existing datasets still cover only a limited number of views or a restricted scale of spaces. In this paper, we introduce Matterport3D, a large-scale RGB-D dataset containing 10,800 panoramic views from 194,400 RGB-D images of 90 building-scale scenes. Annotations are provided with su...
متن کاملMapping Wlan Coverage as a Potential Complementary Source for Gps-based Navigation in Indoor Environments
Enhanced-positioning systems are able to support the acquisition of accurate location information using wireless technology other than the Global Positioning System (GPS). These systems have the potential to supplement GPS where GPS is unreliable. In particular, enhanced-positioning systems can provide location information for navigational support and Location Based Services (LBS) indoors and i...
