Publication number: 20230345199Abstract: A method and a device for criterion-based calibration for localization of mobile devices are described. In an example, sensorial data for a zone in the indoor space is obtained. The zone can have a set of factors influencing a behavior of the sensorial data therein. A component of instantaneous localization in the zone is determined based on the sensorial data by simulating variation of the component. The estimation is evaluated based on a ground truth value of the component and, on the basis thereof, a localization criterion is associated with the zone. The localization criterion is indicative of a selectivity in use of the sensorial data for localizing the mobile device in the zone.Type: ApplicationFiled: April 22, 2022Publication date: October 26, 2023Applicant: Mapsted CorpInventors: Ahmed Mahmood, Sean Huberman, Xuyang Han, Eros Gulo

Publication number: 20220210599Abstract: A method and a device for performing targeted calibration are described. In an example, a first set of spatial data acquired within a predefined region in an indoor space is received. The indoor space is represented as a grid of tessellated polygonal tiles arranged in a hierarchical structure of size-wise arranged polygonal tiles. a preliminary discretized spatial map of the calibrated spatial data in the predefined region is generated by linking the first set of spatial data and the corresponding polygonal tiles for which the spatial data has been acquired. From the preliminary discretized spatial map, a group of polygonal tiles are identified which have density of calibrated spatial data less than a threshold density. For the identified polygonal tiles, a second set of spatial data may be acquired. Based on the preliminary discretized spatial map and the second set of spatial data, a fingerprint map is generated for the indoor space.Type: ApplicationFiled: December 25, 2020Publication date: June 30, 2022Applicant: Mapsted Corp.Inventors: Ahmed Mahmood, Joshua Karon, Sean Huberman, Vera Miller, Eros Gulo, Naiyu Chen
