Xu, Man (author), Wei, S. (author), Zlatanova, S. (author), Zhang, Ruiju (author)At present, 87 % of people's activities are in indoor environment; indoor navigation has become a research issue. As the building structures for people's daily life are more and more complex, many obstacles influence humans' moving. Therefore it is essential to provide an accurate and efficient indoor path planning. Nowadays there are many...conference paper 2017

Xu, M. (author), Wei, S. (author), Zlatanova, S. (author)The demand for indoor navigation is increasingly urgent in many applications such as safe management of underground spaces or location services in complex indoor environment, e.g. shopping centres, airports, museums, underground parking lot and hospitals. Indoor navigation is still a challenging research field, as currently applied indoor...journal article 2016

Liu, L. (author), Xu, W. (author), Penard, W. (author), Zlatanova, S. (author)In this paper, we leverage spatial model to process indoor localization results and then improve the track consisting of measured locations. We elaborate different parts of spatial model such as geometry, topology and semantics, and then present how they contribute to the processing of indoor tracks. The initial results of our experiment reveal...conference paper 2015

Xu, D. (author), Zlatanova, S. (author)Database systems are continuously extending their capabilities to store, process and analyse 3D data. Topological relationships which describe the interaction of objects in space is one of the important spatial issues. However, spatial operators for 3D objects are still insufficient. In this paper we present the development of a new 3D...conference paper 2013
