A method for seamless connection of pictures embedded in electronic map

Abstract

The invention relates to the electronic map field and particularly relates to a seamless connection method for inserting a picture into an electronic map. The method comprises the following steps of: 1) realizing picture initialization data; 2) generating at least three calibrating points which have two kinds of coordinates that are screen coordinates and electronic map coordinates, wherein the calibrating points shall be accurate and representative; 3) calculating a length breadth ratio of the picture through the electronic map and screen coordinates, calculating at least four coordinate positions of the electronic map where the picture is arranged, and calculating and saving a current proportion scale of the electronic map where the map is placed according to the calculated length breadth ratio of the picture; 4) through calibrated data, calculating matching positions for starting the picture and the electronic map according to the position of a current picture of yours, the length breadth ratio, and an electronic map scaling ratio when then electronic map is started; and therefore seamless connection of the picture and the electronic map can be realized. The method is characterized in that innovation is realized on the basis that the relative position of the electronic map is not influenced, a picture inserting function is added, and an absolute positioning function is realized.

Description

technical field [0001] The invention relates to the field of electronic maps, in particular to a method for seamless connection of pictures embedded in electronic maps. Background technique [0002] At present, the relatively mature technology applied in the market is to directly display the electronic map, so that the relative position and trajectory can be known roughly, but it is impossible to judge whether it is in the absolute position. It is only now that pictures and electronic maps are used, and the absolute position can be queried, which is convenient to use. Contents of the invention [0003] In order to solve the above-mentioned technical defect that the absolute position of the electronic map cannot be viewed, the purpose of the present invention is to provide a method for seamless connection of pictures embedded in the electronic map, which is innovative on the basis of not affecting the relative position of the electronic map, increasing Image embedding func...
