Title:
METHOD AND SYSTEM FOR FINGERPRINTING SURVEY
Document Type and Number:
WIPO Patent Application WO/2019/113611
Kind Code:
A3
Abstract:
A survey for building fingerprint maps for an area may be achieved using map information to generate a grid of nodes and links, then transforming the grid to a directed graph, generating an improved tour that entirely traverses the directed graph and providing at least one survey route based at least in part on the tour to a surveyor that will perform the survey route. The provided survey route may be traversed with at least one device having an integrated sensor assembly that outputs data representing motion of the device and recording signal measurements with each device at a plurality of positions to generate a fingerprint map. The traversal of the provided survey route may be assessed through in-route assessment and/or post-route assessment. Depending on the assessment, the provided survey route may be re-traversed or a next survey route may be scheduled.
