Embodiment Construction
[0019] A method for seamless connection of pictures embedded in an electronic map, the method includes the following steps:
[0020] 1) Realize image initialization data. The image is a regional planning map or a screenshot of GoogleEarth plane, and there must be three clear positions on it. The picture format uses Bmp or JPEG;
[0021] 2) Generate 3 calibration points, the calibration points have 2 kinds of coordinates, one is the screen coordinates, the other is the electronic map coordinates, the calibration points are required to be accurate and representative;
[0022] 3) Calculate the aspect ratio of the picture through the electronic map and screen coordinates, the electronic map is a longitude and latitude data map; at the same time, calculate the 4 coordinate positions of the electronic map where the picture is located, and calculate the current position of the electronic map where the picture is based on this scale, and save;
[0023] 4) Through the calibrated data...
