The invention relates to the technical field of indoor positioning, in particular to a method for generating an indoor positioning and navigating map model. The method comprises the steps that crowdsourcing data collected by an inertial measuring sensor set in a first area in a room is obtained; according to the crowdsourcing data, advancing tracks of different users are calculated, and a plurality of movable road signs located in the advancing tracks are obtained; sections are established with the space relation between every two movable road signs; the distribution positions of all the sections in the first area are calculated, and the map model corresponding to the first area is generated according to the distribution positions of all the sections in the first area. According to the method, the map model is automatically generated, manual drawing and maintaining are not needed, and time and labor are saved; meanwhile, due to the fact that the crowdsourcing data has the advantages of being large in data size, wide in information content and good in real-time performance, the map model established according to the crowdsourcing data can be higher in accuracy.
Description
technical field [0001] The invention relates to the technical field of indoor positioning, in particular to a method for generating an indoor positioning navigation map model. Background technique [0002] As the indoor space for people's activities becomes larger and more complex, and the points of interest become more and more abundant, the positioning and navigation requirements of parking lots, shopping malls, airports and other places are becoming increasingly strong. Graph models play an extremely important role in indoor spatial location services, such as indoor assisted positioning, navigation, location-based queries, etc. [0003] Existing indoor map models often rely on manual drawing and maintenance, which is not only time-consuming and labor-intensive, but also prone to errors, resulting in low map model accuracy. Contents of the invention [0004] By providing a method for generating an indoor positioning and navigation map model, the present invention solves...
