In the embodiments of the present application, a building area refers to an area where a building is located on a geographical space. The virtual mark map is obtained by dividing the area of a building according to a certain density and generating a virtual mark for each divided sub-area, namely, geographical position information in the sub-area corresponding to each virtual mark, and each virtual mark also corresponds to label information which is used for describing the indoor layout of the sub-area.

And 104, displaying the virtual marked map marked with the target label information.
In the embodiment of the application, in order to enable a user to know the location of the user in a building area, a virtual marking map marked with the indoor location information of the user may be displayed to the user, and of course, the virtual marking map further includes virtual marks and label information of other sub-areas, and only the indoor location information of the user is marked specially, for example, the indoor location information is highlighted or highlighted in a special color. The user accurately determines the specific position of the user in the building by viewing the virtual mark map on which the indoor position information of the user is displayed and combining the relative positions between the virtual marks adjacent to the indoor position information of the user and the label information.

And 204, acquiring a virtual marking map of a target floor in the building area where the user is located according to the current geographical position information.
In the embodiment of the application, different virtual marked maps can be set for different floors in the same building, so that the virtual marked map of the target floor can be obtained according to the target floor input by a user in practical application, and the accuracy of indoor positioning is further improved.
This step can refer to the detailed description of step 103, which is not repeated herein.

And step 211, determining the target division density according to the attribute labels.
In the embodiment of the present application, the target division density is a density for sub-area division for a building area to be processed. Different division densities are preset aiming at different attribute labels, for example, the attribute labels with larger site orientations such as zoos, markets and airports can be set with smaller division densities, so that virtual marks in certain building regions are fewer, the attribute labels which need to be accurately positioned and need complicated indoor layout such as libraries and museums can be set with larger division densities, so that the virtual marks are correspondingly more, the division densities can be determined according to actual requirements, and the limitation is insufficient.
And 212, dividing the building area to be processed according to the target division density to obtain sub-areas.
According to the embodiment of the application, the areas of different buildings to be processed are divided according to the target division density corresponding to the attribute tags, so that the complexity of data storage of the virtual marking map is further reduced, and the generation efficiency of the virtual marking map is improved.
