Description

technical field [0001] The invention relates to a position determining technology in mobile communication, in particular to a map processing method and device. Background technique [0002] In the existing technology, in the process of using indoor maps in public areas such as large shopping malls, hospitals, exhibitions, airports and railway stations, there will be many situations where the use is not smooth, such as: when the user uses gestures to operate the map to pan, rotate, zoom in and out , the display of the mobile terminal client is stuck; when tapping the screen to select a certain room, the search for the selected room is slow, and the selection is slow, which seriously affects the user experience. [0003] Usually, the reason for these phenomena is: when there is a gesture to operate the map, the mobile terminal such as a mobile phone constantly refreshes the screen at a rate of 60 frames per second, so the map needs to be drawn 60 times per second; The new coo...

Problems solved by technology

However, when drawing large-scale indoor maps, such as exhibition venues and underground parking lots, because the tables and chairs in each room need to be drawn, there will be lag, and the drawing action cannot be completed within 16.6ms

[0004] In addition, when the user clicks a point on the screen and needs to select a room on the screen, it is necessary to traverse all the rooms in the floor in order to determine whether the room corresponding to the clicked point is included. There will be sluggishness
