Method and device for fluent movement of map

Abstract

The embodiment of the invention discloses a method and a device for fluent movement of a map, which are used for realizing the fluent movement of the map. The method disclosed by the embodiment of the invention comprises the following steps of: acquiring a map range to be drawn on a current display interface in a real-time manner; judging whether the map range to be drawn is in a preset reference bitmap or not; displaying the part in the reference bitmap, which corresponds to the map to be drawn, on the current display interface if the map range to be drawn is completely positioned in the reference bitmap; judging whether data corresponding to the map to be drawn is buffered in a data buffer area or not if the map range to be drawn is not positioned in the reference bitmap; acquiring the data corresponding to the map to be drawn from the data buffer area if the data corresponding to the map to be drawn is buffered in the data buffer area; and displaying the corresponding map on the current display interface according to the acquired data. The embodiment of the invention further comprises the device corresponding to the method, which can effectively realize the fluent movement of the map.

Description

technical field [0001] The invention relates to the field of navigation, in particular to a method and device for smooth map movement. Background technique [0002] In the existing navigation technology, the map displayed on the display interface moves with the change of the current position. There are many ways to realize the smooth movement of the map in the prior art. For example, the map is not drawn during the dragging process, and the dragging After the movement stops, obtain the data corresponding to the map on the display interface and redraw the map; or load the data in real time while the map is being dragged. [0003] However, the technical effect of the smooth movement of the map in the prior art is not very good, because the map is updated or the data is loaded in real time after the map stops dragging, so that there is a time difference or data loading in the process of the map being dragged The time is long, the data update of the display interface is slow, t...

Problems solved by technology

[0003] However, the technical effect of the smooth movement of the map in the prior art is not very good, because the map is updated or the data is loaded in real time after the map stops dragging, so that there is a time difference or data loading in the process of the map being dragged The time is long, the update of the display interface data is slow, the time is extended, the efficiency is not high, the smooth movement of the map cannot be well realized, and the needs of users cannot be met.
