Fig. 4 is a schematic diagram of a map interface according to an embodiment of the present invention. Referring to fig. 4, interface 401-interface 404 are included.
It is assumed that a map application is installed in the terminal device.
After the user opens the map application in the terminal device, the map display is performed according to the actual position of the user, so that the user is located at the center of the map, for example, the map displayed by the terminal device may be as shown in the interface 401.
Referring to the interface 401, the map includes a virtual user icon S, and the virtual user icon S is located at the center of the map. The map shown in the interface 401 is a complete map, that is, the user can view all the geographic information through the map shown in the interface 401, but the map shown in the interface 401 does not include detailed geographic information. A "scan" button is also included in the interface 401, and can be clicked by the user to scan the object of interest to the user through the terminal device.
Assume that the actual scene in which the user is located is as shown in interface M, and there is a signpost in the vicinity of the user, indicating that the user is currently on a long-distance road. Assuming that the user needs to check detailed geographic information on the Changan road, the user can click a 'scan' button, and align a camera of the terminal device with the road sign to scan the road sign. See interface 402 for details.
Referring to the interface 402, a scan frame is displayed on the terminal device, and the scanned object (landmark) is displayed in the scan frame. The terminal equipment extracts object information 'Changan road' of the road sign from the road sign. The terminal device transmits the object information (Changan road) to the server. And the server acquires the geographic information in the area indicated by the long safety road according to the object information (the long safety road) and sends the geographic information in the area indicated by the long safety road to the terminal equipment. The geographic information in the indicated area of the Changan road comprises building information and the like on two sides of the Changan road. After the terminal equipment receives the geographic information in the area indicated by the Changan road, the terminal equipment conducts three-dimensional drawing on the geographic information to obtain the detailed geographic condition of the Changan road. Specifically, please refer to the interface 403.
Referring to the interface 403, the detailed geographic information of the Changan road is displayed in the map. Assuming that the user needs to view detailed geographic conditions of other positions on the Changan road, the user can drag the virtual user icon S. After the user drags the virtual user icon S, the terminal device determines that the target position of the user in the map is the position of the virtual user icon S in the map, and redraws the geographic information according to the position of the virtual user icon S in the map to obtain the map shown in the interface 404.
Referring to the interface 404, the redrawn map is displayed in the terminal device. Further, the evaluation information of the user on the entity (e.g. building, etc.) may also be displayed in a blank area of the terminal device, for example, please refer to the interface 403, the user evaluation of the building may be displayed in the blank area of the terminal device: the cool sheet of the second floor is delicious, and the clothes of the third floor are good.
In the embodiment shown in fig. 4, when the user needs to view the detailed geographic condition on the long safe road in the map, the user can scan the road sign on the long safe road, so that the terminal device can draw the geographic information on the long safe road in the map, and the terminal device can only display the detailed geographic condition on the long safe road in the map. Therefore, when the user views the area indicated by the first object through the dragging operation and/or the zooming operation, the situation that the user cannot find the concerned area can be avoided, the map display flexibility is improved, and the use experience of the user on the map is further improved. Furthermore, as the terminal device only displays the geographical condition on the Changan road, the visual interference of the area which is not concerned by the user to the user is avoided, the area range which the terminal device needs to draw in the map is reduced, the terminal device can draw the geographical condition on the Changan road in a limited screen in more detail, the user can know the geographical condition on the Changan road in more detail, and the use experience of the user on the map is further improved.
