Abstract

The invention discloses a method, device and storage medium for automatically constructing an indoor map, wherein the method includes the steps of: obtaining user's indoor movement trajectory data and behavioral landmark data through crowdsourcing, and analyzing the obtained movement trajectory Data and behavioral landmark data are processed for graph optimization and build indoor maps. The invention effectively solves the technical problems in the prior art that the indoor map drawing process data is difficult to obtain, the drawing process is time-consuming and labor-intensive, and cannot accurately reflect the real indoor environment.

Description

technical field [0001] The invention relates to the field of indoor maps, in particular to an indoor map construction method based on crowdsourcing data and graph optimization theory. Background technique [0002] Today, indoor maps have become one of the key elements of indoor location-based service applications such as indoor pedestrian navigation. In traditional indoor map production, building design drawings are usually an important data source, but indoor buildings often belong to different owners. , due to privacy concerns, it is difficult to obtain detailed construction drawings. On the other hand, due to factors such as interior decoration and furniture arrangement, the topological structure of the indoor map often changes, so that the map obtained through the architectural design drawing cannot accurately reflect the real indoor environment. Although the existing indoor map can be updated by manual mapping, this method is very time-consuming and labor-intensive, wh...
